Abstract
Niacin had long been understood as an antioxidant. There were reports that high fat diet (HFD) may cause psychological and physical impairments. The present study was aimed to experience the effect of Niacin on % growth rate, cumulative food intake, motor activity and anxiety profile, redox status, 5-HT metabolism and brain histopathology in rats. Rats were administered with Niacin at a dose of 50 mg/ml/kg body weight for 4 weeks following normal diet (ND) and HFD. Behavioral tests were performed after 4 weeks. Animals were sacrificed to collect brain samples. Biochemical, neurochemical and histopathological studies were performed. HFD increased food intake and body weight. The exploratory activity was reduced and anxiety like behavior was observed in HFD treated animals. Activity of antioxidant enzymes was decreased while oxidative stress marker and serotonin metabolism in the brain of rat were increased in HFD treated animals than ND fed rats. Morphology of the brain was also altered by HFD administration. Conversely, Niacin treated animals decreased food intake and % growth rate, increased exploratory activity, produced anxiolytic effects, decreased oxidative stress and increased antioxidant enzyme and 5-HT levels following HFD. Morphology of brain is also normalized by the treatment of Niacin following HFD. In-silico studies showed that Niacin has a potential binding affinity with degradative enzyme of 5-HT i.e. monoamine oxidase (MAO) A and B with an energy of ~ - 4.5 and - 5.0 kcal/mol respectively. In conclusion, the present study showed that Niacin enhanced motor activity, produced anxiolytic effect, and reduced oxidative stress, appetite, growth rate, increased antioxidant enzymes and normalized serotonin system and brain morphology following HFD intake. In-silico studies suggested that increase 5-HT was associated with the binding of MAO with Niacin subsequentially an inhibition of the degradation of monoamine. It is suggested that Niacin has a great antioxidant potential and could be a good therapy for the treatment of HFD induced obesity.

Abstract
Plants and their parts have been extensively used for the therapeutic purposes such as aging due to their powerful antioxidative belongings. Presently, we intended to examine the consequence of fruit peel of Mukia madrespatana (M.M) on D-galactose (D-Gal) persuaded anxiety and/or depression profile, cognition and serotonin metabolism in rats. Animals were divided in to 4 groups (n = 6). (i) Water treated (ii) D-Gal treated (iii) M.M. treated (iv) D-Gal + M.M. treated. All the animals received their respective treatment for 4 weeks. D-Gal and M.M. fruit peel were given to animals with oral gavage with doses 300 mg/ml/kg/day and 2 g/kg/day respectively. After 4 weeks' behavioral analysis performed to evaluate anxiety and depression profile, cognitive function of animals. After that animals were sacrificed and whole brain removed for biochemical (redox status, degradative enzyme of acetylcholine), and neurochemical (serotonin metabolism) analysis. Results showed that administration of M.M. inhibited D-Gal-instigated anxious and depressive behaviors and improved cognition. Treatment of M.M. decreased MDA levels, AChE activity and increased antioxidant enzyme activity in D-Gal administered and control rats. Enhanced serotonin metabolism also decreased by M.M. in control and D-Gal administered rats. In conclusion, M.M. fruit peel has powerful antioxidative and neuromodulatory properties and due to this effect, it may be a good source of mitigation/treatment for aging induced behavioral and cognitive impairment.

Abstract
L-Cysteine (L-Cys) is a semi-essential amino acid. It serves as a substrate for enzyme cystathionine-β-synthase in the central nervous system (CNS). L-Cys showed various antioxidant characteristics. Though, studies on the effect of free L-Cys administration to evaluate the CNS functioning is very limited. Therefore, we assessed the effects of L-Cys on corticosterone (CORT) induced oxidative stress, behavioral deficits and memory impairment in male rats. L-Cys (150 mg/kg/ml) administered to vehicle and CORT (20 mg/kg/ml) treated rats orally for 28 days. Behavioral activities were conducted after treatment period. Subsequently, rats were sacrificed, blood and brain were removed. Hippocampus was isolated from brain and then hippocampus and plasma were collected for oxidative, biochemical and neurochemical analysis. Results showed that repeated treatment of L-Cys produced antidepressant, anxiolytic and memory-improving effects which may be ascribed to the enhanced antioxidant profile, normalized cholinergic, serotonergic neurotransmission in brain (hippocampus) following CORT administration. Increased plasma CORT by CORT administration was also normalized by L-Cys. The current study concluded that administration of free L-Cys improved the behavioral, biochemical, neurochemical and redox status of CNS. Hence, L-Cys could be protective therapeutic modulator against stress induced neurological ailments.

Abstract
Diabetes is a group of metabolic disorder effecting health of wide number of population and cause neuropsychological decline. In the present study, effect of AI leaves extract on neuropsychological behaviors was observed in diabetic rat's model. Rats were divided into 4 groups as control (saline treated healthy rats), positive control (pioglitazone treated diabetic rats), diabetic control (untreated diabetic rats) and AI leaves extract treated diabetic rats. Diabetes was induced by giving 35% fructose for 6 weeks and a single dose of Streptozotocin (40 mg/kg). After 3 weeks of treatment behavioral and biochemical analysis were done. Behavioral results revealed that induction of type 2 diabetes produced anxiety, depression, decreased motor activity and impaired recognition memory in rats. Treatment with AI leaves extract in diabetic rats significantly decreased anxiety, depression, increased motor activity, enhanced recognition memory. Biochemical investigation revealed that AI leaves extract treat diabetes via improving the levels of fasting insulin and HbA1c and a significant decrease in CK and SGPT levels were observed in AI leaves treated diabetic rats. So, AI besides treating diabetes, helps in lowering the risk of co-occurring diabetic diseases and found effective in lowering neuropsychological decline observed in type 2 diabetes.

Abstract
Aging is the process that every organism faces. The aging model of brain has been developed by the use of d-galactose (d-Gal). Adenosine (Ad) being a neuroprotective agent that has been utilized in treatment of various neurological disorders. The aim of current study is to evaluate the outcome of Ad on d-Gal induced neurotoxicity which caused behavioral deficits, memory impairment and oxidative stress. Rats were treated with d-Gal at a dose of 300 mg/ml/kg and Ad 1 mg/ml/kg; intraperitoneally for 28 days. Behavioral assessment was performed after the treatment period. Animals were sacrificed after behavioral tests and their brains were collected, hippocampus were removed for biochemical and neurochemical analysis. The results showed that administration of Ad ameliorates the negative effects of d-Gal induced aging in various behavioral tests and increased the time spent in the open arm and light box in elevated plus maze (EPM) and light dark activity (LDA) tests respectively indicate anxiolytic effect; increased the mobility time in tail suspension test (TST) shows antidepressant effect; decreased escape latencies in Morris water maze (MWM) acquisition trials, increase entries and time spent in the target quadrant suggests improvement in learning ability of animals. Administration of Ad also decreased malondialdehyde (MDA) levels, increased antioxidant enzymes activity; decreased acetylcholinesterase (AChE) activity, increased 5-hydroxytryptamine (5-HT, serotonin) metabolism and normalized histopathological alteration in the hippocampus. It is concluded that anxiety, depression and memory impairment induced by d-Gal were protected by Ad through its antioxidant and neuro-modulatory effects.

Abstract
Elevated arsenic (As) contamination in drinking water was detected in many areas of Pakistan. The intoxication of As causes various neurological diseases in humans, which can be inhibited by the administration of potent antioxidants. Trace elements are also found in drinking water such as selenium (Se), which possess antioxidant potential. The main purpose of the current study is to find out the protective effect of Se against As toxicity which can cause anxiety- and depression-like behaviors as well as memory impairment. Thirty-six male rats were divided into six groups: (1) distilled water (dw)+dw, (2) dw+Se (0.175 mg/ml/kg), (3) dw+Se (0.35mg/ml/kg), (4) dw+As (2.5mg/ml/kg), (5) As (2.5mg/ml/kg) + Se (0.175 mg/ml/kg), and (6) As (2.5mg/ml/kg) + Se (0.35 mg/ml/kg). Rats were treated with respective treatment for 4 weeks. Sub-chronic treatment of As reduced time spent in open arm (elevated plus maze), and lightbox (light-dark activity test) and increased immobility time in forced swim test indicate anxiety- and/or depression-like behavior, respectively. Conversely, rats treated with As+Se (at both doses) increased time spent in open arm (elevated plus maze), and lightbox (light-dark activity test) and decreased immobility time in forced swim test indicate the anxiolytic and anti-depressive effect of Se, respectively. Co-administration of Se (0.175 and 0.35) inhibited As instigated reduction of spatial memory performed in Morris water maze. The reversal in the reduced level of malondialdehyde and activity of acetylcholinesterase in the hippocampus by Se was observed in As-treated animals, while the activity of antioxidant enzymes in the hippocampus was increased in As+Se than dw+As-treated animals. Histopathological studies have shown the reversal of hippocampus deterioration by Se in As-treated rats. The results may imply to prevent the intoxication of As instigated impairment in behavioral and biochemical indices by Se supplementation and/or increased safer intake.

Abstract
Noise is an environmental stressor which causes distress and hearing loss in individuals residing in urban areas. Psychological deficits such as anxiety, depression, impaired memory and cognitive decline are caused by noise stress. Different vitamins have been used as a potential antioxidant for neuronal protection. In this study we investigate the anxiolytic, antidepressant and memory enhancing effect of vitamin D2 (Vit D2) following noise stress. Thirty-six albino rats were randomly divided into six groups. (i) Unstressed + corn oil (ii) Unstressed + Vit D2 (iii) Acute noise stress + corn oil (iv) Acute noise stress + Vit D2 (v) Repeated noise stress + corn oil (vi) Repeated noise stress + Vit D2. 600 IU/kg body weight of Vit D2 dosage was prepared in corn oil. Corn oil is used as vehicle and all the drugs administered via oral gavage till end of the experiment (day 16). Recorded sound of generator which was amplified by speakers and had 100 dB intensity was used as noise stress. Repeated stressed animals were exposed to noise (4-hrs) daily for 14 days, while acute stressed animals were exposed to noise (4-hrs) once after 14 days. Behavioral tests (elevated plus maze, light dark box, tail suspension test and Morris water maze) of all groups were performed after15 days treatment period. After behavioral tests rats received their last dosage and decapitated after 1-hr. Brain of all animals was removed and used for biochemical (oxidative stress biomarker, antioxidant enzymes and acetylcholinesterase) and histopathological estimations. Results show that Vit D2 decreased time spent in light box and open arm of light dark activity box and elevated plus maze test respectively (used for anxiety evaluation), decreased immobility time in tail suspension test (for depression) and improved cognitive ability evaluated by Morris water maze test in acute and repeated noise stressed rats. Furthermore, increased antioxidant enzymes activity, decreased lipid peroxidation and acetylcholinesterase activity were also observed in Vit D2 treated animals following acute and repeated noise stress. Normalization in histopathological studies was also observed in Vit D2 treated following acute and repeated noise stress. It is concluded that Vit D2 protects from noise stress induced behavioral, biochemical and histopathological impairment through its antioxidant potential.

Abstract
Aging is an ultimate reality that everyone has to face. D-galactose (D-gal) has been used extensively to develop aging model. Trace elements such as selenium (Se) have been used as a potential antioxidant for neuro-protection. The present work aims to develop therapeutic agents such as Se for the treatment of aging-induced neurological ailments such as anxiety, depression, and memory impairment. For this purpose, mice were treated with D-gal at a dose of 300 mg/ml/kg and various doses of Se (0.175 and 0.35mg/ml/kg) for 28 days. Behavioral tests were monitored after treatment days. After the behavioral assessment, mice were decapitated and their brains were collected. Hippocampi were removed from the brain for biochemical, neurochemical, and histopathological analysis. The present findings of behavioral analysis showed that D-gal-induced anxiety- and depression-like symptoms were inhibited by both doses of Se. D-gal-induced memory alteration was also prevented by repeated doses of Se (0.175 and 0.35mg/ml/kg). Biochemical analysis showed that D-gal-induced increase of oxidative stress and inflammatory markers and decrease of antioxidant enzymes and total protein contents in the hippocampus were prevented by Se administration. An increase in the activity of acetylcholinesterase was also diminished by Se. The neurochemical assessment showed that D-gal-induced increased serotonin metabolism and decreased acetylcholine levels in the hippocampus were restored by repeated treatment of Se. Histopathological estimations also exhibited; normalization of D-gal induced neurodegenerative changes. It is concluded that D-gal-induced dysfunction in mice hippocampus caused anxiety, depression, memory impairment, oxidative stress, neuro-inflammation, and histological alterations that were mitigated by Se via its antioxidant potential, anti-inflammatory property, and modulating capability of serotonergic and cholinergic functions.

Abstract
Thymoquinone (Tq), an active compound of Nigella sativa, has been known for its anti-inflammatory, antioxidant, and neuroprotective characteristics. The present study is aimed to evaluate the effect of Tq on reserpine (Rsp)-induced behavioral (anxiety and/or depression) and, memory deficit; hippocampal inflammatory markers, oxidative markers, antioxidant enzymes, acetylcholinesterase (AChE) activity and histopathology in male mice. Animals were injected with Rsp at a dose of 2 mg/ml/kg and doses of Tq (10 and 20 mg/ml/kg) for 28 days. After the treatment period, behavioral tests [Elevated plus maze (Epm); Light dark box test (Lda); Morris water maze (Mwm); Forced swim test (Fst); Tail suspension test (Tst)] were conducted. After analysis of behaviors, mice were decapitated and brain samples were collected, the hippocampus was removed from the whole-brain sample for biochemical analysis and histology. Administration of Tq at both doses prevent adverse effects of Rsp and increased time spent in open arm and lightbox in Lda and Epm respectively, decreased immobility period in Fst and Tst, decreased latency escape in Mwm, reduced lipid peroxidation (lpo) and inflammatory cytokines, increased defensive enzymes, reduced acetylcholinesterase (AChE) activity and corrected histological lines. It is concluded that Rsp-instigated behavioral and memory deficits were prevented by Tq possibly via its strong antioxidant and anti-inflammatory effects.

Abstract
The study is aimed to evaluate the protective impact of banana peel extract (BPE) following noise induce behavioral deficits in male mice. Animals were separated into two groups (control and test, 12 in each). Control mice were given drinking water, at the same time test group was given BPE (400 mg/kg; oral administration). Animals have received their respective treatment for 14 days. Mice were subdivided (n=6) into unstressed and stressed groups on day 15. Noise stress was given to the respective group for 4-h. Behavioral activities were monitored 24-h after the 4-h noise stress. Forced-swim-test, Elevated-plus-maze and light-dark-activity-box tests were performed for depression/anxiety-like behaviors respectively. Morris-water-maze assessment was used for memory. After behavioral tests animals were sacrificed and brain was detached for biochemical estimations and histopathological studies. In the present study, BPE produced anxiolytic and antidepressant-like effects and enhanced memory. Activity of antioxidant enzymes increased while levels of AChE and MDA decreased in BPE treated animals. Histopathological alterations induced by noise stress were also normalized by BPE. It is concluded that supplementation/administration of banana peel has preventive effects against anxiety, depression and memory impairment via its strong antioxidant potential following NS.

Abstract
Nanotechnology is a field of science that consists of atoms, molecules and supramolecular molecules that create nanoparticles ranging in size from 1-100nm. Silver nanoparticles are widely used that are considered as effective antimicrobial agents. In this paper, the antioxidant activity of biosynthesized SNPs were analyzed by the DPPPH activity, hydrogen peroxide activity, hydroxyl RSA, TAC, TFC; their results confirmed that the phenolic compounds of this plant peels extracts enhanced the antioxidant and antiglycation activity with respect to silver nanoparticles. Biosynthesized nanoparticles of this plant extracts also showed strong zone of inhibition against the different Xanthomas, Pseudomonas and E. coli. This study concluded that biosynthesized nanoparticles of Mukia maderaspatna (M.M) plant peels extracts have the great biological activities i.e. antiglycation, antioxidant and antibacterial. More research is needed to know the exact dose rate and to compare the different dose combination of the plant with the strong antibiotic agents against these bacteria.

Abstract
Reserpine (Res)-induced depletion of monoamines and altered neurotransmission and produces oxidative stress. Tryptophan (TRP) regulated the serotonin neurotransmission. Because systemically injected Res induced behavioral deficits and oxidative stress, while, dietary components prevented these adverse effects, we used TRP a pharmacological tool to prevent Res- induced changes in behavior, memory impairments, oxidative stress and regulation of serotonin neurotransmission in rats. Anxiolytic, antidepressant, cognitive functions, lipid peroxidation, antioxidant enzymes serotonin metabolism were studied in Res and vehicle treated animals following administration of 50 and 100 mg/ml/kg of tryptophan. Following administration of TRP [50 and 100mg/ml/kg], Res induced anxiety-and/or depression like behaviors normalized. Res-induced impaired cognitive function and increased acetylcholinesterase activity also improved following administration of TRP at both doses. Res induced increased brains' malondialdehyde (MDA) and decreased antioxidant enzymes activity also normalized by TRP. Res-induced decreased 5-HT metabolism also regulated by administration of TRP at both doses. In conclusion it can be recommended that administration/supplementation of TRP in daily life can aid in battling the anxiety, depression, modulating serotonergic activity and oxidative stress. Study also exhibits the anti-acetylcholinesterase role of TRP which may be possible reason for improved cognition following stress situation.

Abstract
SUMMARY Insulin autoimmune syndrome (IAS) is a rare cause of non-islet cell hypoglycaemia. Treatment of this condition is complex and typically involves long-term use of glucocorticoids. Immunotherapy may provide an alternative in the management of this autoimmune condition through the suppression of antibodies production by B-lymphocyte depletion. We present a case of a 62-year-old male, with refractory hypoglycaemia initially presenting with hypoglycaemic seizure during an admission for acute psychosis. Biochemical testing revealed hypoglycaemia with an inappropriately elevated insulin and C-peptide level and no evidence of exogenous use of insulin or sulphonylurea. Polyethylene glycol precipitation demonstrated persistently elevated free insulin levels. This was accompanied by markedly elevated anti-insulin antibody (IA) titres. Imaging included CT with contrast, MRI, pancreatic endoscopic ultrasound and Ga 68-DOTATATE position emission tomography (DOTATATE PET) scan did not reveal islet cell aetiology for hyperinsulinaemia. Maintenance of euglycaemia was dependent on oral steroids and dextrose infusion. Complete resolution of hypoglycaemia and dependence on glucose and steroids was only achieved following treatment with plasma exchange and rituximab. LEARNING POINTS Insulin autoimmune syndrome (IAS) should be considered in patients with recurrent hyperinsulinaemic hypoglycaemia in whom exogenous insulin administration and islet cell pathologies have been excluded. Biochemical techniques play an essential role in establishing high insulin concentration, insulin antibody titres, and eliminating biochemical interference. High insulin antibody concentration can lead to inappropriately elevated serum insulin levels leading to hypoglycaemia. Plasma exchange and B-lymphocyte depletion with rituximab and immunosuppression with high dose glucocorticoids are effective in reducing serum insulin levels and hypoglycaemia in insulin autoimmune syndrome (IAS). Based on our observation, the reduction in serum insulin level may be a better indicator of treatment efficacy compared to anti-insulin antibody (IA) titre as it demonstrated greater correlation to the frequency of hypoglycaemia and to hypoglycaemia resolution.

Abstract
During neuronal diseases, neuronal proteins get disturbed due to changes in the connections of neurons. As a result, neuronal proteins get disturbed and cause epilepsy. At the genetic level, many mutations may take place in proteins like axon guidance proteins, leucine-rich glioma inactivated 1 protein, microtubular protein, pore-forming, chromatin remodeling, and chemokine proteins which may lead toward temporal lobe epilepsy. These proteins can be targeted in the future for the treatment purpose of epilepsy. Novel avenues can be developed for therapeutic interventions by these new insights.

Abstract
Grewia asiatica L. fruit natively called phalsa is a popular berry of Pakistan and widely consumed in the form of fresh juices and carbonated drinks in the summer season. The berry is enriched with antioxidants such as phenols, flavonoids, anthocyanins, and vitamin C. Scientifically, it is the least explored berry in terms of neuromodulatory activities, and therefore, in the designed study, chronically fed rats with the different dilutions (5%-30%) of fruit juice were subjected to behavioral assessment for anxiety, depression, and cognition (spatial memory) followed by biochemical analysis of isolated brains. Results revealed a prominent impact of 20 and 30% dilutions of fruit exudate as treated animals showed anxiolytic behavior to central zone (P < 0.05) of open field test (OFT) and open arms of elevated plus maze (EPM) (P < 0.05) in anxiety models. Overall, immobility of rats treated with a higher concentration of exudate in forced swim test (FST) was reduced (P < 0.05) presenting antidepressant-like activity. Moreover, in learning and memory experimental models, the treated animals reversed scopolamine-induced amnesic effects as evident from improved step-through latencies (P < 0.05 vs. scopolamine; passive avoidance test), spontaneous alternation behavior (P < 0.05 vs. scopolamine; Y-maze test), discrimination index (P < 0.05 vs. scopolamine; novel object recognition test), and escape latencies (P < 0.05 vs. scopolamine; Morris water maze). Biochemical studies of isolated brains from treated rats demonstrated significantly elevated levels of superoxide dismutase and glutathione peroxidase (P < 0.05), whereas levels of acetylcholinesterase and malondialdehyde level (P < 0.05) were reduced, indicating its potential to reduce oxidative damage in the brain and modulation with the cholinergic system. The outcomes of studies support the benefits of phytoconstituents possessed by G. asiatica fruit in the amelioration of neurological disorders that could be due to their antioxidative capacity or due to interaction with GABAergic, serotonergic, and cholinergic systems in the brain.

Abstract
The lithium-pilocarpine model in rats is commonly used to study the characteristic events of acute status epilepticus (SE), epileptogenesis and temporal lobe epilepsy (TLE). Here we investigated the impact of lacosamide alone and in combination with other drugs (pregabalin, piracetam and scopolamine) on spontaneous recurrent seizures (SRSs) and behavioral parameters during the time frame of 6 weeks after SE. In addition, the level of oxidative stress in the hippocampus was accessed by real-time microdialysis study (8-isoprostanes) and antioxidants enzymes in the homogenate. Results revealed severe behavioral deficits with the control epileptic group and animals displayed hyperexcitability, aggression apprehension and memory insufficiency. Pharmacological manipulation for 6 weeks with lacosamide (L) - 80 mg/kg; in polypharmacy with pregabalin (L/P) - 50/50 mg/kg and piracetam (L/Pi) - 50/140 mg/kg significantly (P < 0.05) ameliorated the anxiety-related behavior (open filed, elevated plus maze, light/dark tests), depression (forced swim test) and improved spatial/reference memory (Morris water maze). There were low incidences of seizures in L, L/P and L/Pi groups revealing disease-modifying effects of employed drugs. Furthermore, the chronic use of scopolamine (L/P/S; 50/50/2 mg/kg) as polypharmacy with the concept of antagonizing the cholinergic inputs in the epileptogenic phase aberrated the behavioral situation further worse. Treatments with L/P and L/Pi significantly attenuated (P < 0.05) the oxidative stress by reducing 8-isoprostanes and malondialdehyde (MDA) levels. Furthermore, superoxide dismutase (SOD) and glutathione peroxidase (GPx) levels in the L/P group were significantly (P < 0.05) improved. Overall, our findings support the use of a combination of drugs (L/P and L/Pi) in lithium-pilocarpine model which remarkably ameliorated SRSs, reduced anxiety-related behaviors, retention of spatial/reference memory and lowered oxidative stress in a time-course evaluation 6 weeks post- SE insult.

Abstract
The current study was designed to determine the outcome of banana fruit pulp (BFP) on repeated noise stress exposure (NSE)-induced behavioral deficits and oxidative stress in male mice. BFP (600mg/kg b.w) was administered orally once daily for 2 weeks prior exposure to noise stress. Mice were exposed to NS for 4 h after administration of BFP for 2 weeks. Control mice were administered drinking water and similar treatment as given to test animals. At the end of the treatment behavioral changes were monitored. Animals were sacrificed following behavioral assessment and the brain and plasma samples were collected for biochemical analysis. Repeated NS-induced behavioral deficits (anxiety and depression), impaired learning and memory and produced oxidative stress. Administration of BFP inhibited NS-induced behavioral deficits (anxiolytic and antidepressant effects) and improved cognitive abilities. Brain lipid per oxidation was also decreased with concomitant increase of antioxidant enzyme activities. Repeated noise stress increased plasma corticosterone levels. A significant decrease of plasma corticosterone was observed on unstressed BFP treated animals while this decrease was comparable in stressed + BFP animals. Decreased levels of acetylcholinesterase in BPF+NS treated animals indicated increased cholinergic function which improves learning and memory. Repeated oral administration of BFP induced cognitive improving ability, anti-stress effect and potentiated antioxidant defence mechanism in both control and NS mice. Thus, it is suggested that dietary supplementation of BFP has a curative effect against NS-induced psychiatric and cognitive related disorders which merits deliberation and additional appraisal.

Abstract
BACKGROUND AND OBJECTIVES Elevated oxidative stress has been shown to play an important role in the diagnosis and prognosis of stress and memory-related complications. Mukia madrespatana (M. madrespatana) has been reported to have various biological and antioxidant properties. We intended to evaluate the effect of M. madrespatana peel on single immobilization stress-induced behavioral deficits and memory changes in rats. Materials and Methods: M. madrespatana peel (2000 mg/kg/day, orally) was administered to control and immobilize stressed animals for 4 weeks. Anxiolytic, antidepressant, and memory-enhancing effects of M. madrespatana were observed in both unstressed and stressed animals. Results: Lipid peroxidation was decreased while antioxidant enzymes were increased in both unstressed and stressed animals. Acetylcholine level was increased while acetylcholinesterase activity was decreased in both M. madrespatana treated unstressed and stressed rats. There was also an improvement in memory function. Serotonin neurotransmission was also regulated in M. madrespatana treated rats following immobilization stress with anxiolytic and anti-depressive effects. Conclusion: Based on the current study, it is suggested that M. madrespatana has strong antioxidant properties and may be beneficial as dietary supplementation in stress and memory-related conditions.

Abstract
The aging process is concerned with oxidative stress and causing malfunction of various organs such as the liver, kidney and heart. Lithium (Li) salts have shown anti-manic, anti-suicidal, and antioxidant properties. The current study is aimed to evaluate the possible inhibitory effects of various doses (10, 20 & 40mg/ml/kg) of Lithium chloride (LiCl) on D-galactose (D-gal)-produced aging model and explore the underlying mechanism. In the study 40 male rats were randomly alienated into 8 groups i.e. saline, LiCl (10, 20 & 40mg/ml/kg), D-gal and D-gal+LiCl (10, 20 & 40 mg/ml/kg). D-gal was given at a dosage of 300mg/ml/kg$ and animals received their respective treatment for 6 weeks [intraperitoneally (I.P), once daily]. After 2 weeks animals were decapitated and organs (liver, kidney, and heart) were removed for antioxidant assays. Blood was also collected for biochemical parameters. LiCl substantially decreased oxidative strain marker and increased enzymatic antioxidants in the liver, kidney, and heart of D-gal treated rats. LiCl also decreased serum alanine aminotransferase (ALT), aspartate transaminase (AST), creatine, urea, CK-MB, triglyceride, cholesterol, low-density lipoprotein (LDL) and increased high-density lipoprotein (HDL) in D-gal treated animals. High dose (80mg/ml/kg) of LiCl observed as the most effective dose against D-gal induced alterations. These finding LiCl inhibits D-gal induced liver, kidney and heart damages via its antioxidant potential.

Abstract
In 30% of epileptic individuals, intractable epilepsy represents a problem for the management of seizures and severely affects the patient's quality of life due to pharmacoresistance with commonly used antiseizure drugs (ASDs). Surgery is not the best option for all resistant patients due to its post-surgical consequences. Therefore, several alternative or complementary therapies have scientifically proven significant therapeutic potential for the management of seizures in intractable epilepsy patients with seizure-free occurrences. Various non-pharmacological interventions include metabolic therapy, brain stimulation therapy, and complementary therapy. Metabolic therapy works out by altering the energy metabolites and include the ketogenic diets (KD) (that is restricted in carbohydrates and mimics the metabolic state of the body as produced during fasting and exerts its antiepileptic effect) and anaplerotic diet (which revives the level of TCA cycle intermediates and this is responsible for its effect). Neuromodulation therapy includes vagus nerve stimulation (VNS), responsive neurostimulation therapy (RNS) and transcranial magnetic stimulation therapy (TMS). Complementary therapies such as biofeedback and music therapy have demonstrated promising results in pharmacoresistant epilepsies. The current emphasis of the review article is to explore the different integrated mechanisms of various treatments for adequate seizure control, and their limitations, and supportive pieces of evidence that show the efficacy and tolerability of these non-pharmacological options.

Abstract
Background and Objectives: Ficus benghalensis (FB) is a commonly found tree in Pakistan and its various parts have folkloric importance in managing neurological ailments. In the present study, methanolic extract of its bark has been tested on an experimental animal model to evaluate memory-enhancing, anxiolytic and antidepressant activities to validate the claimed therapeutic potential. Materials and Methods: Methanolic extract of freshly isolated bark was prepared and subjected to preliminary phytochemical studies and gas chromatography-mass spectrometry (GC-MS) analysis for the presence of phytocomponents. To evaluate its effect on spatial learning, passive-avoidance test-step through (PAT-ST), Y-maze and Morris water maze (MWM) tests were carried out. Open-field (OFT) and elevated plus maze (EPM) tests were employed to explore the anti-anxiety potential of FB while a forced swimming test (FST) was utilized to assess its anti-depressant prospective. FB doses of 100, 200 and 300 mg/kg with positive and negative controls given to Sprague Dawley (SD) rats. Results: phytochemical studies showed the presence of various phytoconstituents including alkaloids, flavonoids, terpenes, phenolics and anthraquinones. The presence of synephrine, aspargine, glucose, fructose and fatty acids was revealed by GC-MS analysis. FB administration led to significant improved memory retention when evaluated through passive avoidance (p < 0.05), Y-maze (p < 0.05) and Morris water maze (p < 0.05) tests in a scopolamine model of amnesic rats. When tested by open field and elevated plus maze tests, FB demonstrated anxiety-resolving characteristics (p < 0.05) as animals dared to stay in open areas more than a control group. Mobility time was increased and immobility time was reduced (p < 0.05-0.01) in rats treated with FB, unveiling the anti-depressant importance of F. benghalensis. Conclusion: methanolic extract of F. benghalensis bark furnished scientific proof behind folkloric claims of the memory improving, anxiety-reducing and depression-resolving characteristics of the plant. These activities might be possible due to interaction of its phytoconstituents with serotonergic, glutamatergic, cholinergic and GABAergic systems in the brain.

Abstract
Hypertension is considered as a multifactorial disorder in which a numerous of physiological mechanism take part to raise blood pressure The present study is carried out to study the serum and red blood cell electrolytes disturbances in men and women patients of essential hypertension. The samples for analysis were obtained from two hundred four (204) age and sex matched volunteers (51 men and 51 women normotensive, 51 men and 51 women hypertensive). Erythrocytes obtained from blood samples (freshly drawn), washed and processed for the estimation of Na+ and K+ concentrations through flame photometer. Biochemical estimations were done by flame photometery and spectrophotometery. Data were analyzed by Two-way ANOVA followed by Newman-Keuls test. Results show the intra-erythrocyte sodium levels were significantly higher in essential hypertension patients than normotensive healthy controls. Whereas serum concentrations of sodium, potassium, calcium, magnesium, phosphorus and intraerythrocyte potassium were significantly smaller in hypertensive patients with respect to normotensive control subjects. Moreover, systolic, diastolic blood pressure and intraerythrocyte sodium were higher while potassium was lower in hypertensive women compared to hypertensive men. From a clinical point of view, an inverse correlation was found between systolic blood pressure values and serum Na+, K+, Ca2+ and Mg2+ in the sample of essential hypertensive patients. No sex related differences were observed in serum electrolytes in normal individual and patients of essential hypertension. The results reported here suggest that serum magnesium and its interactions with monovalent cations e.g. sodium, potassium, phosphorus, RBC sodium and RBC potassium and divalent cations like calcium are the main responsible ions for the pathogenesis of hypertension. Intraerythrocyte levels of sodium perform an important role in the greater vulnerability of male sex to develop hypertension.

Abstract
OBJECTIVE Depression is a prevalent condition that is costly to individuals and society. In view of a role of tryptophan (TRP), selenium (Se), vitamin D (Vit D), magnesium (Mg) and serotonin in depression, the present study concerns to evaluate the circulating levels of TRP, Se, Vit D, Mg and serotonin in depression as well as the correlation between TRP and other serum analytes is also established. METHODS Healthy (n=48) and depressed (n=48) subjects were recruited and their blood samples were obtained after an overnight fast of 12 h, serum was stored for the determination of levels of TRP, Se, Vit D, Mg, and serotonin. RESULTS Results show that levels of TRP, Se, Vit D, Mg, and serotonin were decreased in the depressed patient when compared to normal subjects. There is a direct correlation between TRP and Vit D, and TRP and Se while the inverse correlation between TRP and Mg, and TRP and serotonin in depressed subjects. The association among TRP and other biomarkers is non-significant. CONCLUSION In conclusion, depression is associated with deficiency of TRP, Se, Vit D, Mg, and serotonin displays the characteristics of biomarkers. The correlation between TRP and other biomarkers/trace elements is also important in depression.

Abstract
BACKGROUND Aging is a phenomenon that all living organisms surely face. d-galactose (D-gal) has been used to develop an aging model of brain. Lithium (Li) has been proposed to have neuroprotective properties in relation to several neurological disorders. The goal of the current studyis to evaluate the effect of Lithium Chloride (LiCl) on D-gal induced neurological disorders and oxidative stress. METHODS Rats were treated with D-gal at a dose of 300 mg/ml/kg and various doses of LiCl (20, 40 and 80 mg/ml/kg) for 14 days. After that behavioral analysis (Elevated plus maze (EPM); Light dark box test (LDT); Morris water maze (MWM); Forced swim test (FST)) were performed. Animals were decapitated after behavioral tests and brain samples were collected for biochemical (malondialdehyde (MDA); superoxide dismutase (SOD); catalase (CAT); glutathione peroxidase (GPx); acetylcholiesterase (AChE)) and neurochemical analysis (5-hydroxytryptamine (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA)). RESULTS The results showed that administration of LiCl at all doses ameliorates D-gal induced, decreased time spent in the open arm and light box in EPM and LDT respectively, increased immobility in FST, increased latency escape in MWM, increased MDA levels, decreased antioxidant enzyme, increased AChE activity and decreased 5-HT metabolism. CONCLUSIONS In conclusion, the present study indicated that D-gal induced anxiety/depression like symptoms and memory impairment were ameliorated by LiCl (at all doses) possibly via its antioxidant effects and normalizing 5-HT function.

Abstract
The purpose of the present study is to determine the effects of gallic acid (GA) on sodium arsenite (iAS)-induced behavior deficits and memory alteration in male rats. Thirty six animals were divided in to 6 groups (six animals in each) (i) saline+saline; (ii) saline+GA (50 mg/kg); (iii) saline+ GA (100 mg/kg) (iv) iAS + saline; (v) iAS + GA(50 mg/kg); (vi) iAS + GA (100 mg/kg). Animals were treated with iAS (2.5 mg/kg/ml); GA (50 and 100 mg/kg/ml) and saline (0.9%; 1 ml/kg) for 4 weeks. Repeated administration of iAS increases immobility time in forced swim test and decreases time spent in open arm (elevated plus maze) and light box (light dark activity box test) suggests depression like and anxiety-like symptoms respectively. On the other hand, animals treated with iAS + GA decreases immobility time and increases time spent in open arm and light box than saline+iAS treated animals suggests anxiolytic and antidepressant-like behavior of GA. Repeated administration of iAS also involves in memory impairment as observed in the Morris water maze test that is reversed by co-administration of GA, indicates that GA also involves in the enhancement of memory. Brain malondialdehyde (MDA) levels, antioxidant enzymes and acetylcholinesterase (AChE) activities also observed in the present study. Results show that iAS produces oxidative stress by increasing lipid peroxidation and decreasing antioxidant enzyme activity. Conversely co-administration of GA produces antioxidant effects by normalization of oxidative stress induced by iAS. Alteration in iAS induced AChE activity is also reversed by GA. It is suggested that GA via its antioxidant potential, has protective effects on iAS induced behavioral deficits and memory alteration. The findings have a strong implication on iAS induced neurological diseases, such as depression, anxiety, Alzheimer's disease and dementia etc.

Abstract
The present study evaluates the protective role of Quercetin (Quer), against immobilization stress- induced anxiety, depression and cognition alteration in mice using behavioral and biochemical parameters. 24 adult Albino mice were distributed into 2 groups vehicle (n=12; 1 ml/kg) and Quer injected (n=12; 20 mg/kg/ml). The animals received their respective treatment for 14 days. On day 15, after the drug administration, animals were sub-divided into 4 groups (n=6); (i) unstressed + vehicle; (ii) stressed + vehicle; (iii) unstressed + Quer; (iv) stressed + Quer. On day 16, 24 h after the immobilization stress behavioral activities (light-dark activity, elevated plus maze, Morris water maze, and forced swim test) monitored and then animals were decapitated 1 h after the drug administration. Brain samples were collected for biochemical (antioxidant enzymes, AChE, ACh, 5-HT and its metabolite) analysis. The present study indicates the Quer reversed the stress-induced anxiety and depression, in addition, memory performance was more enhanced in stressed group. Following the treatment of Quer, stress-induced elevation of lipid peroxidation and suppression of antioxidant enzymes were also reversed. Administration of Quer decreased AChE in unstressed, while levels of acetylcholine were increased in vehicle and Quer treated stressed animals. The metabolism of 5-HT was increased in Quer treated stressed than unstressed animals. In conclusion, the present finding showed that Quer could prevent the impairment of antioxidant enzymes and also regulate the serotonergic and cholinergic neurotransmission and produce antianxiety, antidepressant effect and enhance memory following 2 h immobilization stress in mice.

It plays an important role to improve and control a number of psychiatric disorders such as depression, anxiety, hyperactivity and behavioral impulsivity. Anorexia Nervosa (AN) is one of the psychiatric disorder which is associated with diet. In AN, patients show extreme dieting, weight loss, hyperactivity, depression/anxiety, self-control and behavioral impulsivity. Previous studies showed that during diet restriction, tryptophan decreases serotonin (5-hydroxytryptamine; 5-HT) metabolism in the brain due to its less availability and contributes psychiatric problems associated with AN. The present study is designed to investigate the effects of tryptophan administration on 5-HT metabolism in diet-restricted rats. Tryptophan at a dose of 50 or 100mg/kg was given orally to respective freely fed (FF) or diet restricted (DR) animals daily for five weeks. Behavioral activities were also monitored weekly. The results show significant effect (p<0.05) on behavior in activity box, open field and in light/dark transition test by tryptophan administration in diet-restricted rats. This may be associated with the increased in serum tryptophan and brain 5-HT metabolism. Therefore, it is concluded that diet-restriction-induced behavioral changes might be reverted back with the administration of tryptophan and may be helpful to improve psychological problems in AN.

Abstract
In view of anxiolytic, antidepressant and memory strengthen properties of Allium cepa (AC; onion) bulb in various investigations; we aimed to evaluate the useful effects of onion on single immobilization stress -induced biochemical and behavioral changes. Mice in test group were treated with AC powder (200 mg/kg/day), dissolved in water, while the control group were received drinking water for 14 days. After 14 days control and AC treated mice were further divided into unstressed and stressed groups. Animals in the stressed group were subjected to immobilization stress for 2 h. 24-h after the immobilization stress, behavioral activities were monitored. Immobilization stress-induced an anxiogenic behavior in mice subjected to elevated plus maze test (EPM) and light dark activity test (LDA). 2-h immobilization stress-induced depressive behavior in animals measured by forced swim test (FST). Administration of AC attenuated the immobilization stress-induced behavioral deficits. Highest memory performance was observed in stressed mice that were pre-treated with AC in Morris water maze (MWM). Brain lipid peroxidation, antioxidant enzymes (SOD, CAT, GPx) and acetylcholinesterase (AChE) activities were also estimated. Present study suggests a role of antioxidant enzymes in the attenuation of 2-h stress induced anxiety and depression, and enhanced cognitive function as well by AC. The findings therefore suggest that supplementation of AC may be beneficial in the treatment of anxiety, depression and enhancement of memory function.

Abstract
This study is systematic review of the research, focused on all possible pathways involved in calcium (Ca2+) regulation in order to utilize them in the control and remediation of Alzheimer's disease (AD), because Ca2+ plays important role in pathogenesis of AD. Electronic databases, Science Direct and PubMed/Medline, for relevant publications between 2000April 2017, were searched. Ca2+ ions are very important in cell signaling in body, specially the neuronal signaling. Many pathways are involved in normal neuronal Ca2+ signaling. AD is one of the most commonly known neurodegenerative disorders, causing dementia and some other neuropathological signs in mostly elderly people reaching a rate of 44 million until now. Depending upon certain possibilities, many hypothesis were proposed related to AD; out of which, one is Ca2+ hypothesis. According to this hypothesis, disturbance in Ca2+ signaling pathway due to certain reasons, such as accumulation of beta-amyloid proteins, ER stress, cytochrome c activation etc., causes AD. Due to less clinical research, only few FDAapproved pharmaceuticals are available for treatment of AD. Reviewed studies suggest that Ca2+ channel blocker and initiator may play an important role in cure of AD.

Abstract
The obesity epidemic has turn into a major health threat worldwide and extensively responsible for the increased incidence of many diseases such as diabetes, cardiovascular disease and certain types of cancer. Excessive food intake along with the insufficient physical exercise is the basic impetus for this development. The aim of the present study is to evaluate the serum levels of leptin, zinc and tryptophan (TRP) in obese and non-obese subjects, which play major role in obesity. With the verbal and written consent eighty men were identified from the various areas of Karachi, Pakistan. The socio-demographic data including; age, body mass index (BMI), education and residence, of participants was collected. After providing informed consent, fasting blood samples were taken and serum was collected. The serum concentration of leptin, zinc and TRP were analyzed by ELISA (Enzyme-linked immunosorbent assay), FAAS (Flame atomic absorption spectrophotometer) and HPLC (High performance liquid chromatography) respectively. Results showed that levels of leptin were increased in obese than non-obese subjects significantly. On the other hand levels of zinc and TRP were significantly decreased in obese than non-obese subjects. Furthermore, there was a positive correlation found among leptin, zinc and TRP with obesity. Based on these facts the involvement of leptin, zinc and TRP with obesity will be discussed.

Abstract
Tardive dyskinesia (TD) is associated with the use of antipsychotic drugs such as D2 antagonist haloperidol (HP). The chronic use of HP is involved in the causation of free radicals and/or oxidative stress. In view of the nootropic, anti-anxiety, anti-inflammatory-like effects of rice bran oil (RBO) in a variety of investigations, we assessed the protective properties of RBO on HP-induced TD and neurochemical alteration. Rats treated with HP orally at a dose of 0.2 mg/kg/day for a period of 5 weeks developed VCMs which increased progressively as the treatment continued for 5 weeks. Co-administration of RBO by oral tubes at a dose of 0.4 ml/day prevented the induction of HP-induced VCMs. Repeated administration of HP increases the turnover of dopamine metabolism in the striatum. Conversely animals treated with HP + RBO decrease the metabolism of DA than water + HP treated animals. Striatal, malondieldehyde (MDA), hydrogen peroxide (H2O2) and antioxidant enzyme superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) were also determined. It is suggested that beneficial role of RBO in attenuation of HP-induced TD. The results therefore recommended that supplementation of RBO may be useful in the HP-induced TD. The findings have also potential implication in the treatment of schizophrenia and motor disorders.

Abstract
Obesity is an important risk factor for sleep disorders. This study aimed to evaluate the association of leptin, zinc and tryptophan (TRP) in obese subjects with sleep deficits [sleep apnea (SA), insomnia (IN)]. In this cross sectional case control, with the verbal and written consent 206, obese with sleep deficits and 30, non-obese/normal identified from various areas of Karachi, Pakistan. The socio-demographic data including; age, body mass index (BMI), education and residence, of participants was collected. After providing informed consent, fasting blood samples were taken and serum was collected. The serum concentration of leptin, zinc and TRP were analyzed by ELISA (Enzyme-linked immunosorbent assay), FAAS (Flame atomic absorption spectrophotometer) and HPLC (High performance liquid chromatography) respectively. A significant correlation was found between BMI (body mass index) and leptin, BMI and zinc, BMI and TRP. The correlation between leptin consecutively was significantly associated with zinc and TRP in obese patients. Sleep deficits elevated circulatory levels of leptin while lower zinc and TRP levels compared to levels seen in non-obese (Normal) subjects with no sleep deficits. Obese subjects exhibited significantly higher levels of leptin with sleep deficits compared with non-obese subjects with normal sleep pattern, while obese subjects with SA had significantly high levels of leptin than obese subjects with IN and IN+SA. Patients with sleep deficits had significantly lower levels of serum TRP and zinc than non-obese subjects with normal sleep pattern. Obese subjects with SA had significantly lower levels of zinc and elevated levels of TRP than obese subjects with IN. Obese patients with IN+SA had significantly lower levels of leptin and zinc than IN and SA , while TRP levels were significantly lower in subjects with IN than obese subjects with IN+SA and IN. These results suggest that elevated levels of leptin which are possibly by adiposity and lessened levels of zinc and TRP have a great impact on progression of obesity and their association can contribute to tempt sleep disorders.

Abstract
The present study was aimed to investigate the anti-stress and memory enhancing effects of banana (Musa sapientum L.) fruit pulp and peel extract in male mice. Locally bred albino Wistar mice were divided into control and 2 test groups (n=10). Control rats received drinking water while test groups were treated with banana fruit pulp (600 mg/kg; oral administration) and extract of banana peel (400mg/kg; oral administration). Behavioral activities of animals were monitored 14 days post administration of banana pulp and peel extract. Depression-like symptoms were measured by forced swimming test (FST). Anxiety like behavior was monitored using light-dark activity (LDA) test and plus maze activity (PMA) test and memory functions of rats were assessed by morris water maze (MWM) test. Following 2 weeks animals were decapitated and brain was removed for estimation of antioxidant enzymes such as catalase (CAT), super oxide dismutase (SOD) and reduced glutathione (GSH). In the present study both banana peel and pulp increased the time spent in light box and open arm, suggesting anxiolytic effects. A significant decrease in immobility time was observed in FST in both banana pulp and peel treated animals suggesting antidepressant like effects. Moreover, learning and memory assessed by MWM showed decrease in time to reach platform in both short term and long term memory test suggested increased memory function in both banana pulp and peel treated animals as compared to control animals. The activities of all antioxidant enzymes were significantly (p<0.05) greater in banana pulp and peel treated animals than control. It is concluded that both banana pulp and peel have anti-anxiety, antidepressant effect as well as strengthen the memory possibly via its antioxidant mechanism. Therefore, it is recommended that supplementation of banana could be taken a vital role in stress (anxiety and depression) relief and increased in memory function possibly by phyto-antioxidants.

Abstract
OBJECTIVE To evaluate the biochemical consequences and platelet counts of birth asphyxia in neonates. STUDY DESIGN Cohort study. PLACE AND DURATION OF STUDY Department of Child Health, Nishter Medical College and Hospital, Multan, from September to November 2015. METHODOLOGY The data of 50 (50%) asphyxiated neonates and 50 (50%) non-asphyxiated neonates, with age range less than 1 month, was collected from Children Ward of Nishtar Hospital, Multan, Pakistan. Data on platelet count in blood, kidney function tests (creatinine, urea), liver function tests (bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST)) and cardiac enzyme test (lactate dehydrogenase (LDH)) were analysed by paired sample t-test by SPSS software. Sociodemographic data of those neonate's mothers was also collected. RESULTS In asphyxiated neonates LDH, ALT, AST, creatinine, bilirubin, urea levels were higher than healthy infants, while the platelet count was smaller in asphyxiated neonates than healthy infants. CONCLUSION There was a higher rate of alteration in platelet count, levels of LDH, AST, ALT, urea creatinine and bilirubin in asphyxiated infants. These alterations may be correlated with damage of vital organ of asphyxiated neonates.

Abstract
Outcome of imipramine (IMI) treatment was scrutinized on progression of haloperidol instigated tardive dyskinesia (TD). 0.2 mg/kg/rat dosage of haloperidol provided orally to rats for 2 weeks enhanced vacuous chewing movements that escalated when the process proceeded for 5 weeks. Following 2 weeks co-injection 5 mg/kg dosage of IMI was diminished haloperidol-instigated VCMs and fully averted following five weeks. The potency of 8-OH-DPAT-instigated locomotor activity exhibited higher in saline+haloperidol treated rats while not observed in IMI+ haloperidol treated rats. 8-OH-DPAT-instigated low 5-hydroxytryptamine (5-HT; serotonin) metabolism was higher in saline+ haloperidol treated rats when compare to IMI+ haloperidol treated rats in both regions of brain (striatum and midbrain). It is recommended that IMI possibly competent in averting TD, in cases receiving treatment to antipsychotics.

Abstract
BACKGROUND Achieving adequate glycaemic control in patients with diabetes on peritoneal dialysis is challenging. Traditional assessment of glycaemia using HbA1c is difficult in such patients because of renal anaemia or carbamylation of haemoglobin, and significant glucose excursions may be masked. We describe three patients with diabetes on peritoneal dialysis with similar HbA1c levels, but with very different glucose profiles shown on continuous glucose monitoring. CASE REPORTS Patient 1 was treated with gliclazide, and had a number of solutions with high glucose concentration in his dialysis prescription. Continuous glucose monitoring showed glucose levels > 11 mmol/l for > 17 h per day, and < 4 mmol/l for 72 min per day with no symptoms. His HbA1c level was 61 mmol/mol (7.7%). Patient 2 was treated with insulin. Continuous glucose monitoring showed glucose levels > 11 mmol/mol for 3.8 h per day, and < 4 mmol/mol for 3.8 h per day. His HbA1c level was 59 mmol/mol (7.6%). Patient 3 was treated with pioglitazone and gliclazide, and glucose levels were > 11 mmol/l for 8 h per day and < 4 mmol/l for 1.6 h per day. His HbA1c was 62 mmol/mol (7.8%). None of the patients was aware of hypoglycaemia during the periods of low glucose recorded on continuous glucose monitoring. CONCLUSION Despite similar HbA1c levels, our three patients had very different glucose profiles. These cases highlight the fact that HbA1c is frequently inadequate in reflecting glucose control in patients with diabetes on peritoneal dialysis, and we suggest that intermittent continuous glucose monitoring may allow safer management of glycaemia in such patients.

Abstract
Effect of administration of Rice bran oil (RBO) was evaluated on haloperidol elicited tardive dyskinesia in rats. Albino Wistar rats treated with haloperidol in drinking water at a dose of 0.2mg/kg/day and RBO by oral tubes at a dose of 0.4 mL/day for 5 weeks. Motor coordination, VCMs and 8-hydroxy-2-(di-n-propylamino) tetraline)[8-OH-DPAT] _syndrome were monitored. Striatal serotonin (5-hydroxytryptamine; 5-HT) and 5-hydroxyindolacetic acid (5-HIAA) levels were determined by high performance liquid chromatography (HPLC-EC). Rats treated with haloperidol orally at a dose of for a period of 5 weeks developed VCMs, which increased progressively as the treatment continued for 5 weeks. Motor coordination impairment started after the 1st week and was maximally impaired after 3 weeks and gradually returned to the 1st week value. Co-administration of RBO prevented haloperidol_induced VCMs as well impairment of motor coordination. The intensity of 8-OH-DPAT_induced syndrome and decreased 5-HT metabolism were greater in water + haloperidol treated animals than RBO + haloperidol treated animals. The present study suggested that involvement of free radical in the development of TD and point to RBO as a possible therapeutic option to treat this hyperkinetic motor disorder.

Abstract
Effects of administration of imipramine (IMI) are determined on haloperidol-induced extrapyramidal symptoms (EPS). Haloperidol is administered orally at a dose of 0.2 mg/rat/day in rats for a period of 5 weeks, by this treatment rats developed vacuous chewing movements (VCMs) after 2 weeks, which increased in a time dependent manner as the treatment continued for 5 weeks. Motor coordination (assess on rota rod activity) impaired maximally after 3 weeks and tolerance was developed in the haloperidol induced motor impairment after 5 weeks of treatment. Motor activity in an open field or activity box was not altered. The administration of IMI (intraperitoneally, for 5 weeks) did not affect motor activity or motor coordination. Co-administration of IMI at a dose of 5 mg/ml/kg/day attenuated the induction of haloperidol elicited VCMs (Quantitative orofacial dyskinesia) as well impairment of motor coordination. Results are discussed in the context of the mechanism involved by which imipramine attenuated haloperidol-induced EPS.

Abstract
8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT), a selective 5-hydroxy-tryptamine (5-HT; serotonin)-1A agonist was used to evaluate the role 5-HT-1 A receptors in restraint-induced behavioral deficits and adaptation to repeated restraint stress in rats. Animals were injected with 8-OH-DPAT at a dose of 0.25 mg/kg 1 h before exposing to an episode of 2 h/day restraint stress daily for 5 days. Effects of drug administration and restraint stress on 24 h cumulative food intakes were monitored daily. Intensity of 8-OH-DPAT-induced serotonin syndrome was also monitored each day before submitting animals to the episode of stress. Exposure to the first episode of 2 h restraint stress resulted in a decrease in 24 h cumulative food intake and an attenuation of 8-OH-DPAT-induced serotonin syndrome monitored next day. The deficits attenuated following 2nd and 3rd 2 h/day restraint were not observed following the 4th and 5th 2 h/day restraint. The decreases of food intake following 1st and 2nd day restraint sessions were smaller in 8-OH-DPAT than saline-injected animals. Administration of 8-OH-DPAT on day 6 elicited comparable serotonin syndrome in unrestrained and repeatedly restrained groups. Brain 5-HT metabolism decreased in unrestrained but not repeatedly restrained animals. The results suggest that a decrease in serotonergic neurotransmission is involved in restraint-induced behavioral deficits while a normalization of serotonin neurotransmission due to desensitization of somatodendritic 5-HT-1A receptors may help cope with the stress demand to produce adaptation to stress.

Abstract
The present study was designed to monitor the responsiveness of 5-hydroxytryptamine (5-HT; serotonin)-2C receptors following the exposure to restraint stress in rats. Rats were restrained for 2 hours. 24-h after the termination of the restraint period, 1-(m-Chlorophenyl)piperazine (m-CPP; a 5-HT-2C agonist) at the doses of 1.5 mg/kg or 3.0 mg/kg and saline (1 ml/kg), was injected to unrestrained and restrained animals. Hypolocomotive effects (home cage activity, open field activity and motor coordination) and anxiogenic-like effects (light-dark activity and plus maze activity) were successively monitored in each animal after the drug or saline administration. Rats were decapitated 1-h post-injection to collect brain samples for neurochemical estimation by HPLC-EC. Our results show that differences in the hypolocomotive and anxiogenic-like effects of m-CPP between restrained and unrestrained animals could not be demonstrated in the present experimental paradigm. This was due to the fact that the behavioral effects were already marked after restraint leaving little room for an additional m-CPP effect. The effects of m-CPP on increasing 5-hydroxyindole acetic acid (5-HIAA) and decreasing dihydroxy phenyl acetic acid (DOPAC) levels were more pronounced (p < 0.01) in restrained than unrestrained animals. The results suggest that behavioral responses to m-CPP and stress are similar The attenuation of m-CPP changes in 5-HIAA and DOPAC levels may be due to a decreased responsiveness of 5-HT-2C receptors in restrained animals.
