Abstract
Abstract In current study, different feeding levels of Moringa oleifera formulated diet was compared to analyze the growth performance, feed conversion ratio, feed conversion efficiency and gut microbiology of Oreochromis niloticus. The study was comprised of four treatment groups including 4%, 8% and 12% Moringa oleifera and one control group which was devoid of Moringa leaves. The experimental trial was conducted at the Zoology laboratory of Pakistan Institute of Applied and Social Sciences, (PIASS) Kasur. The physicochemical parameters of water such as temperature, dissolve oxygen, pH, total dissolved solids and salinity in all aquaria were found non-significantly different from each other. In control condition T1, the average weight gain was 14.89±16.90a grams, while average length gain was 11.52±7.444a cm. However, the total viable count on Eosin methylene blue was 7.4×107, 5.8×107 on Tryptic soy agar and 5.8×107on Nutrient agar. In T2, the average weight gain was 16.22±16.09b grams and average length gain was 12.97±7.79b cm. The total viable count on Eosin methylene blue was 7×107, 5.5×107 on Tryptic soy agar and 5.8×107on Nutrient agar. In T3, the average weight gain was 37.88±27.43c grams, while the average length gain was recorded as 16.48±12.56c cm. However, the total viable count for treatment 3 was 6.4×10 on Eosin methylene blue, 4.8×107 on Tryptic soy agar and 5.2×107on Nutrient agar. In T4, the average weight gain was 44.22±31.67d grams, while the average length gain was 15.25±10.49d cm. The total viable count was 4.3×107on Eosin methylene blue, 3.1×107 on Tryptic soy agar and 3.8×107 on Nutrient agar. The effect of Moringa oleifera on the growth of Oreochromis niloticus was found to be significant and 12% Moringa extract showed maximum length and weight gain and minimum feed conversion ratio with the least microbial count in fish intestine.

Abstract
In this comparative cross-sectional study, we compare the physical performance among post-COVID and non-COVID subjects. A sample of 64 subjects recovered from COVID-19 and 64 subjects who were not infected with COVID-19 were recruited for the study. Both groups were tested for physical performance by 30-s sit-to-stand test, 6-min walk test, and HUMAC balance system. The findings of the present study reveal that there was a significant difference in physical performance between both the groups. In conclusion, this study demonstrated that physical performance is impaired in the post-COVID subjects as compared to the matched non-COVID subjects. Therefore, physical therapy exercise program/regimen should be a part of recovery from COVID-19.

Abstract
Abstract Bauhinia variegata plant is a very popular and traditionally potent ethnomedicine. Therefore, it is need of hour to study ameliorative characteristics of B. variegata for novel secondary metabolites. The current study was designed to explore antiproliferative potential of B. variegata due to scant reports on this aspect. Extracts of various parts (flowers, leaves, bark, stem, and roots) were prepared by successive maceration using organic solvents in increasing order of polarity (n-hexane, ethyl acetate, methanol, and water). The determination of polyphenolic contents was done by using colorimetric methods while antioxidant potential was measured using reducing power assay. Brine shrimp lethality assay was performed for determining preliminary cytotoxicity and antiproliferative activity against breast cancer MCF-7 cell line using MTT protocols. Moreover, antimicrobial activities were detected by using disc diffusion assay. The alpha-amylase assay was performed to monitor the antidiabetic potential of the plant. In case of phytochemical analysis methanolic extract of leaves and bark showed highest phenolic and flavonoids contents. n-Hexane and ethyl acetate extracts of stem and roots exhibited more than 90% mortality with LD50 ranges between 1-25 µg/mL when studied by brine shrimp lethality assay. n-Hexane and ethyl acetate extracts of roots and stem also showed antiproliferative activity against human breast cancer MCF-7 cell line with IC50 values ranges between 12.10-14.20 µg/mL. Most of the extracts displayed moderately high antibacterial and antifungal activities. The n-hexane extract of roots showed antidiabetic activity with 60.80 ± 0.20% inhibition of alpha-amylase. In sum, these preliminary results will be useful for further compound isolation from selected plant parts for the discovery of antibacterial, antidiabetic, and anticancer lead candidates.

Abstract
Abstract
Background
The cardiovascular manifestations of idiopathic pulmonary fibrosis (IPF) include heart failure, pulmonary hypertension, coronary artery disease, cardiac arrhythmias and cardiac manifestations of drugs used to treat IPF. Cardiac disease can be worsened by hypoxia and pulmonary hypertension by IPF. The impact of IPF on the outcomes of acute decompensated heart failure (ADHF) is not well studied.
Purpose
We aim to determine the outcomes of patients admitted for ADHF with co-morbid IPF.
Methods
Data were extracted from the National Inpatient Sample (NIS) 2016 - 2018 Database. The NIS was searched for hospitalizations for adult patients with ADHF as principal discharge diagnosis with and without IPF as secondary diagnosis using ICD-10 codes. The primary outcome was inpatient mortality. Secondary outcomes are detailed in table 1. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. A univariate screen was done to further confirm that these factors affected outcomes with variables having a p-value less than 0.2 included in the multivariate regression analysis. STATA software was used to for analysis.
Results
Of 1,007,824 patients admitted for ADHF, 1850 (0.2%) had IPF. Patients with IPF were significantly younger at the time of hospitalization for ADHF (71 years vs. 76 years, p<0.001). There were 46% females in IPF group compared to 48% in the non-IPF group, p=0.451. The adjusted odds ratio (aOR) for inpatient mortality for ADHF with IPF compared to those without IPF was 2.82 (95% CI 1.897–4.215, p<0.001). Patients with comorbid IPF had 1 day increase in mean length of stay (95% CI 0.475–1.525, p<0.001). Detailed outcomes are listed in table 1.
Conclusions
Co-morbid IPF leads to higher inpatient mortality and higher length of hospitalization in patients with acute decompensated heart failure. It is prudent to risk stratify these patients to improve overall morbidity and mortality.

Abstract
Abstract
Background
Type 2 diabetes mellitus (T2DM) is an important risk factor for, and a frequent co-existing condition with heart failure (HF). With increasing prevalence of heart failure and type 2 diabetes, patients with concomitant HF and T2DM have worse clinical outcomes.
Purpose
We sought to determine the in-patient mortality for type 2 diabetics admitted for heart failure in the U.S hospitals from 2008 to 2018.
Methods
Data were extracted from the National Inpatient Sample (NIS) 2008 to 2018 Database. The NIS was searched for hospitalizations for adult patients with heart failure as principal discharge diagnosis with type 2 diabetes mellitus as a secondary diagnosis using ICD-9 and ICD-10 codes. The primary outcome was inpatient mortality. Multivariate logistic regression analysis was used determine the impact of evolving demographic characteristics (age, sex and race/ethnicity) on in-hospital mortality. STATA software was used to for analysis.
Results
Hospitalization with a primary discharge diagnosis of heart failure steadily decreased from 1,011,094 in 2008 to 807,764 in 2016 and 139,315 in 2018. The patient characteristics of hospitalizations for heart failure in type 2 diabetics are shown in table 1. Adjusted in-hospital mortality in HF with T2DM decreased significantly from 2008 to 2018 (3.6% in 2008 to 2.0% in 2018, P trend 0.003) as shown in graph 1.
Conclusion
Hospitalization for heart failure decreased steadily from 2008 to 2018 in the United States. In-hospital mortality rate for type 2 diabetics admitted for heart failure decreased significantly from 2008 to 2018.

Abstract
Tacrolimus (TAC) is the drug of choice in immunosuppressive therapy for organ transplantation; however, adverse effects are still a major concern. The current study aims to decipher the short-term exposure of TAC on rat hepatocytes in relation to activation of hedgehog (HH) signaling pathway. Time dependent study was conducted using primary rat hepatocytes treated with TAC (36 µM) for 6, 12, 24 and 48 h. Western blot analysis was performed using cell lysate in order to analyze the regulation of HH pathway proteins including HHIP, SMO, PTCH, IHH, SHH, and GLI transcription factors. The study revealed change in protein expression of HH signaling molecules with activation of HH pathway, due to downregulation of HHIP, and enrichment of HH ligands with activation of SMO and GLI transcription factors. It is therefore, concluded that short term TAC exposure leads to upregulation of HH pathway in liver, which may initially act to repair the liver damage but can worsen the condition in case of prolonged immunosuppressive therapy. This insight could lead to understand association of off target effects of immunosuppressive drugs and occurrence of other liver diseases in transplant patients when it comes to long term immunosuppressive therapy. These findings also illuminate a novel direction that use of HH inhibitor might provide a therapeutic strategy for immune suppression related liver disorders.

1. Background
Implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRT-D) are indicated in primary and secondary prevention of dysrhythmias among other indications. We sought to determine the impact of chronic kidney disease (CKD) on hospitalizations for ICD or CRT-D placement.
2. Purpose
Determine how CKD impacts in-patient mortality and cardiovascular outcomes in patients undergoing ICD or CRT-D placement while hospitalized.
3. Methods
Data were extracted from the National Inpatient Sample (NIS) 2016 - 2018 Database. The NIS was searched for patients who underwent ICD or CRT-D placement. The patients were divided into two groups based on presence or absence of CKD as secondary diagnosis using ICD-10 codes. The primary outcome was inpatient mortality. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders (A univariate screen was done to confirm the confounders affected outcomes with variables having a p less than 0.2 were included in the multivariate regression analysis). STATA software was used to for analysis.
4. Results
Of 145,550 patients admitted for ICD or CRT-D placement, 47740 (32.8%) had CKD. The adjusted odds ratio (aOR) for inpatient mortality for patients undergoing ICD or CRT-D placement with co-morbid CKD compared to those without CKD was 1.66 (95% CI 1.194 – 2.329, p = 0.003). Patients with comorbid CKD had lower odds of developing cardiogenic shock (aOR: 0.83, 95% CI 0.718 – 0.948, p = 0.007) and cardiac arrest (aOR: 0.88, 95% CI 0.766 – 0.999, p = 0.048) compared to patients without CKD. Detailed outcomes are listed in table 1.
5. Conclusion
Chronic kidney disease is a risk factor associated with increased in-patient mortality in patients admitted for ICD or CRT-D placement.

1. Introduction
Obesity causes significant cardiovascular morbidity. Nonetheless, there is also evidence supporting obesity paradox particularly in heart failure patients. The impact of obesity on the outcomes of patients undergoing pacemaker insertion is not well studied.
2. Purpose
The purpose of this study is to determine if obesity paradox exists for the patients who undergo pacemaker insertion.
3. Methods
Data were extracted from the National Inpatient Sample (NIS) 2016 - 2018 Database. The NIS was searched for patients who underwent pacemaker insertion while hospitalized. The patients were divided into two groups based on presence or absence of obesity as secondary diagnosis using ICD-10 codes. The primary outcome was inpatient mortality. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. STATA software was used to for analysis.
4. Results
Of 408,040 patients who underwent pacemaker insertion, 64185 (15.7%) were obese. The adjusted odds ratio for inpatient mortality for obese patient undergoing pacemaker insertion compared to non-obese patients was 0.65 (95% CI 0.516 – 0.821, p < 0.001). Secondary outcomes are listed in table 1.
5. Conclusion
Obese patients who underwent pacemaker insertion had lower inpatient mortality compared to non-obese patients. Also, obese patients undergoing pacemaker insertion were less likely to have cardiac arrest but they were more likely to develop decompensated heart failure and acute renal failure compared to non-obese patients.

Abstract
Background: Therapy that targets cancer stem cells has the potential to eradicate cancer and prevent tumour recurrence. Therefore, we hypothesized the combined prognostic significance of stem cell markers CD44 (prevalent in basal layer of urothelial carcinoma) and Nanog (embryonic stem cell transcription factor) in bladder cancer.Material and Methods: CD44 and Nanog expression were determined by immunohistochemistry in 112 bladder cancer cases of which 79 were non-muscle invasive and 33 muscle invasive.Results: A significant correlation was found between CD44 and Nanog expression (r = 0.41, p < 0.001). The bladder cancer patients with high CD44 and Nanog expression had poor recurrence-free survival and poor overall survival (all p < 0.01). Multivariate Cox regression analysis identified lymph node positivity (hazard ratio; HR 3.81, 95% confidence interval; CI 1.66-8.75), CD44 (HR/95%CI 7.03 [3.04-16.22]) and Nanog (HR/95%CI 2.89 [1.23-6.77]) as independent prognostic biomarkers for recurrence-free survival, whilst a combined index of CD44 and Nanog expression (high expression group; HR/95%CI 25.45 [6.71-96.50] for recurrence-free survival) and lymph node positivity (HR/95%CI 3.68 [1.63-8.33] for recurrence-free survival) were independent prognostic biomarkers for recurrence-free survival and overall survival (all p < 0.001).Conclusions: A combined index of CD44 and Nanog expression is a promising prognostic predictor of recurrence-free survival and overall survival in bladder cancer. It may help identification of patients who will benefit from intensive treatment.

Abstract
OBJECTIVE In this study, we report acute blood transfusion reactions at our hospital, compare our analysis with the reported data and identify areas for improvement. BACKGROUND Haemovigilance programmes have been implemented in many countries, and adverse events associated with blood transfusion are published in their annual reports. Pakistan has no current established programme. MATERIAL AND METHODS A cross-sectional study was conducted, and all adverse reactions reported to the blood bank from January 2014 to March 2016 were included. An adverse response in the patient, related to administration of blood (within 24 h), was considered an immediate transfusion reaction. RESULTS During the study period, 20 956 blood components were issued. A total of 32 (0·15%) adverse reactions were documented. Allergic reactions were the most common adverse event observed in 15 (46·8%) of the cases. Febrile non-haemolytic transfusion reaction (FNHTR) was the second most common reaction seen in nine (28%) followed by bacterial contamination in four (12·5%) and acute haemolytic reaction in two (6·2%) of the cases. CONCLUSION The low incidence indicates underreporting and the need for a formal haemovigilance system. International benchmarking between different medical systems is helpful to identify areas in the transfusion process that have to be changed to improve transfusion safety.

Abstract
Glanzmann thrombasthenia (GT) is an inherited genetic disorder affecting platelets, which is characterized by spontaneous mucocutaneous bleeding and abnormally prolonged bleeding in response to injury or trauma. The underlying defect is failure of platelet aggregation due to qualitative and/or quantitative deficiency of platelet integrin αIIbβ3 resulting from molecular genetic defects in either ITGA2B or ITGB3. Here, we examine a Pakistani cohort of 15 patients with clinical symptoms of GT who underwent laboratory and molecular genetic analysis. In patients with a broad range of disease severity and age of presentation, we identified pathogenic mutations in ITGA2B in 11 patients from 8 different families, including 2 novel homozygous mutations and 1 novel heterozygous mutation. Mutations in ITGB3 were identified in 4 patients from 3 families, two of which were novel homozygous truncating mutations. A molecular genetic diagnosis was established in 11 families with GT, including 5 novel mutations extending the spectrum of mutations in this disease within a region of the world where little is known about the incidence of GT. Mutational analysis is a key component of a complete diagnosis of GT and allows appropriate management and screening of other family members to be performed.

Abstract
Asymptomatic post-menopausal osteoporosis is common but some-times associated with pain and deformity. Symptomatic osteoporosis is usually associated with fracture. A 59 years old post-menopausal woman presented with a history of acute low-back-pain. She had menopause for 12 years. She gave history of colles' fracture at about two years back. Her mother died as consequences of femoral neck fracture. MRI of vertebral spine showed demineralization with partial collapse of D6,7,12 and L1 vertebra. Dual energy X-ray absorptiometry of vertebra showed BMD T-score of -4.5. Patient was managed with IV infusion of zoledronic acid, oral intake of vitamin D and calcium supplements and with regular non-weight-bearing exercises. Her condition improved gradually. During post-menopausal period, every women must be aware of osteoporosis and any fracture in that time must be evaluated to rule out osteoporosis.

Abstract
Tuftsin, a naturally occurring tetrapeptide with a sequence Thr-Lys-Pro-Arg was evaluated for its in vivo protective effect against cyclophosphamide-induced genotoxicity and oxidative stress in Swiss albino mice. The anticancer drug cyclophosphamide (CP) was administered intra-peritonially to induce mutagenic effect. The drug treatment caused significant increase in chromosomal aberrations, formation of micronucleated polychromatic erythrocytes (MNPCE's), as well as oxidative stress and decrease in lipid peroxidation in liver of the animals. The pretreatment with tuftsin abolished such effects in dose-dependent manner and also increased mitotic index in the experimental animals. Results of the present study validated chemo-preventive properties of tuftsin against CP-induced chromosomal mutations and cellular injury of liver by oxidative stress.

Abstract
Berberine has been shown to have hypoglycaemic activity in several in vitro and in vivo models, although the mechanism of action is not fully known. Berberis lyceum Royle root produces high concentrations of berberine, and in traditional medicine, the whole extract of this plant is used widely to treat diabetes. The antidiabetic activity of the ethanol root extract of Berberis lyceum was compared with pure berberine in normal and alloxan-diabetic rats using similar doses of each. The concentration of berberine in the extract was determined to be 80% dry weight with only trace amounts of other alkaloids present. The purpose of the study was to investigate the effects of berberine and a whole extract of Berberis lyceum on blood glucose and other parameters associated with diabetes, to compare the effects of the crude extract with those of pure berberine and thus validate its use as a therapeutic agent, and finally to identify any contribution of the other components of the extract to these effects. Oral administration of 50 mg/kg of Berberis extract and berberine to normal and experimental diabetic rats produced a significant (p < 0.05) reduction in blood glucose levels from days 3-7 days of treatment. Significant effects were also observed on the glucose tolerance, glycosylated haemoglobin, serum lipid profiles and body weight of experimental animals. Berberis extract and berberine demonstrated similar effects on all parameters measured, and although the extract was comparable in efficacy to berberine, it did not produce any effects additional to those shown by pure berberine. The results support the use of the extract in traditional medicine, and demonstrate that apart from being a highly cost-effective means of treating with berberine, the total extract does not appear to confer any additional benefits or disadvantages compared with the pure compound.

Abstract
A number of alkyl 5(6)-(substituted-carbamoyl)- and 5(6)-(disubstituted-carbamoyl)benzimidazole-2-carbamates and related compounds have been synthesized, and their anthelmintic activity against various intestinal helminths of experimental animals have been evaluated. A large percentage of the compounds synthesized showed noteworthy activity against Ancylostoma ceylanicum and at higher doses against Hymenolepsis nana infections. Compared to the alkyl 5(6)-(substituted-carbamoyl)benzimidazole-2-carbamates, the disubstituted carbamoyl analogues were found to exhibit better anthelmintic activity. The most active compound of the series, namely, methyl 5(6)-[(N-2-pyridylpiperazino)carbamoyl]benzimidazole-2-carbamate (90), has been screened against intestinal helminths in higher animals and as a micro- and macrofilaricidal agent. Compound 90 has been identified as a broad-spectrum anthelmintic agent. Compound 90 has been identified as a broad-spectrum anthelmintic in view of its efficacy against A. ceylanicum (hamsters and dogs), H. nana (rats), Nippostrongylus brasiliensis (rats), Syphacia obvelata (mice), A. tubaeformis (cat), Toxocara spp. (cat), and Litomosoides carinii (cotton rat).

Abstract
BACKGROUND Chemotherapy is the basic approach to clinical tuberculosis control. Antituberculous therapy causes derangement of hepatic functions revealed by disturbed liver function tests. The incidence of side effects may vary depending upon a number of factors. The primary purpose of this study was to determine the relative and absolute hepatotoxicity of different antituberculous drug regimens in Pakistani population where majority of the tuberculous patients belong to poor socioeconomic status. METHODS One hundred patients between 30 to 70 years of age with newly diagnosed pulmonary tuberculosis were selected and divided into four groups on the basis of different drug regimens. Blood and urine tests of these patients were made. Liver function tests were performed before therapy and then after one, two, three, six and nine months of treatment. RESULTS & CONCLUSIONS Antituberculous therapy causes derangement of hepatic function to a variable extent in patients of four different antituberculous drug regimens under study. Drug combination of Streptomycin, Isoniazid and Myambutol seem to be best tolerated of all the four regimens. Monitoring of the liver function in patients on antituberculous therapy indicated that liver dysfunction most frequently occurs during first three months of therapy. There is a tendency for enzyme values to return to normal inspite of continuous treatment. The mechanism underlying this adaptation to injury to the liver is unknown. Biochemical tests in the patients presenting with jaundice yielded the pattern of acute hepatocellular necrosis with high transaminases and moderately elevated Alkaline Phosphatase. None of the patients had hepatitis associated antigen in their serum.

Abstract
Quinolones have been discovered in our laboratory as a new class of antifilarial agents. This has led to the design, synthesis, and antifilarial evaluation of a number of N-substituted quinol-4(1H)-one-3-carboxamide derivatives 4-6. The macrofilaricidal activity of the target compounds was initially evaluated in vivo against Acanthoeilonema viteae by oral administration of 200 mg/kg x 5 days. Among all the synthesized compounds, 13 displayed activity, with the most potent compound (4a) exhibiting 100% macrofilaricidal and 90% microfilaricidal activities. Compound 4e elicited significant macrofilaricidal (80%) response while compound 5c showed 100% sterilization of female worms. Finally, the two most potent macrofilaricidal compounds, namely 4a and 4e, have been screened for their potency against DNA topoisomerase II, and it has been observed that both have the capability to interfere with this enzyme at 10 micromol/mL concentration. The structure-activity relationship (SAR) associated with position-3 and aryl ring substituents is discussed.

Abstract
Substituted 9H-pyrido[3,4-b]indoles (beta-carbolines) identified in our laboratory as potential pharmacophore for designing macrofilaricidal agents, have been explored further for identifying the pharmacophore responsible for high order of adulticidal activity. This has led to syntheses and macrofilaricidal evaluations of a number of 1-aryl-9H-pyrido[3,4-b]indole-3-carboxylate derivatives (3-7). The macrofilarical activity was initially evaluated in vivo against Acanthoeilonema viteae. Amongst all the synthesized compounds, only twelve compounds namely 3a, 3c, 3d, 3f, 4c, 4d, 4f, 5a, 6f, 6h, 6i and 7h have exhibited either > 90% micro- or macrofilaricidal activity or sterilization of female worms. These compounds have also been screened against Litomosoides carinii and of these only 3f and 5a have also been found to be active. Finally these two compounds have been evaluated against Brugia malayi. The structure activity relationship (SAR) associated with position-1 and 3 substituents in beta-carbolines have been discussed. It has been observed that the presence of carbomethoxy at position-3 and an aryl substituent at position- in beta-carbolines effectively enhance antifilarial activity particularly against A. viteae. Amongst the various compounds screened, methyl 1-(4-methylphenyl)-9H-pyrido[3,4-b]indole-3-carboxylate (4c) has shown highest adulticidal activity and methyl 1-(4-chlorophenyl)-1,2,3,4-tetrahydro-9H-pyrido[3,4-b]indole-3-carboxyla te (3a) has shown highest microfilaricidal action against A. viteae at 50 mg/ kg x 5 days (i.p.). Another derivative of this compound namely 1-(4-chlorophenyl)-3-hydroxymethyl-9H-pyrido[3,4-b]indole (5a) exhibited highest activity against L. carinii at 30 mg/kg x 5 days (i.p.) and against B. malayi at 50 mg/kg x 5 days (i.p.) or at 200 mg/kg x 5 days (p.o.).

Abstract
The contribution of N-linked glycosylation to the ligand binding activity of the rat luteinizing hormone receptor (LHR) was studied in wild-type and mutant LHR expressed in mammalian (COS1) cells and overexpressed in insect (Sf9) cells. The binding affinities of the holoreceptor and its truncated splice variant (form B) lacking the transmembrane domain were equivalent in both cell lines. Tunicamycin-treated transfected Sf9 cells expressed a carbohydrate-free LH receptor that lacked hormone binding activity. Functional carbohydrate chains essential for binding activity were localized to glycosylation sites at Asn-173 and Asn-152. Glycosidase treatment of the double mutant N173Q/N152Q revealed the presence of at least one additional carbohydrate chain at Asn-269, Asn-277, or Asn-291 that does not contribute to hormone binding. Asn-77 was not glycosylated, but its mutation to Gln reduced hormone binding. LHR expressed in insect cells contained only high mannose carbohydrate chains, and those located at Asn-173 and Asn-152 were sufficient for high-affinity hormone binding. Enzymatic cleavage of glycosyl chains indicated that only the proximal N-acetylglucosamine residue, which is common to high mannose and complex carbohydrate forms, is necessary for acquisition of the high affinity conformation of the receptor. The carbohydrate chains of the LHR appear to be involved in intramolecular folding of the nascent receptor rather than in its interaction with the hormone.

Abstract
The activity of alpha-anilinobenzyl cyanides (2a-f), 5-aryl-4,5-dihydro-2-methoxycarbonylamino-1-phenylimidazoles (5a-d) and 2-methoxycarbonylamino-1-phenyl-1,3-diazaspiro[4:5]dec-2-ene (5f) have been tested for their micro- and macrofilaricidal activity against Litomosoides carinii and Acanthocheilonema viteae in rodents. In this test alpha-anilinobenzyl cyanides (2a-b), 5-(4-methoxyphenyl)-4,5-dihydro-2-methoxy-carbonylamino-1-phenylim idazole (5b) and 2-methoxycarbonylamino-1-phenyl-1,3-diazaspiro[4:5]dec-2-ene (5f) were found to possess marked filaricidal activity at doses ranging from 3-100 mg/kg given parenterally or orally for 5 days.

Abstract
Calcium silicate has been considered as a possible replacement for asbestos due to its heat and fire resistance. We describe the cytotoxic and genotoxic potential of calcium silicate using peripheral human blood lymphocytes. Calcium silicates at concentrations of 10 and 100 micrograms/ml significantly increased the frequencies of chromosomal aberrations (CAs) and sister-chromatid exchanges (SCEs). The increases in CAs and SCEs were dose-dependent, though not linearly. A significant decrease in the proliferation rate index was observed with increased dose of calcium silicates. The induction of chromatid-type aberrations indicates that the clastogenic activity of calcium silicate is S-phase-dependent.

Abstract
The effect of three anticalmodulin drugs, prepared in this laboratory and a commercially available drug Mastoparan, was tested on the secretion (or synthesis) of testosterone in hCG stimulated Leydig cells. The results of the use of drugs RN-IV A, RN-IV B and RN-IV C indicated that hCG (10 ng/ml), DbcAMP (0.1 mM) and cholera toxin (2 micrograms/ml)-stimulated testosterone production was inhibited in Leydig cells in a dose dependent manner. In hCG stimulated cells, the ID50 for drug RN-IV A was 2 microM, for drug RN-IV B was 25 microM and for drug RN-IV C was 130 microM. Based on ID50 the most effective drug was RN-IV A. Maximum inhibition of testosterone production was obtained at a concentration of 20 microM for drug RN-IV A, 150 microM for drug RN-IV B and 200 microM for drug RN-IV C. Further extensive experiments with drug RN-IV B showed that (a) at 100 microM concentration the drug does not impair the binding of receptor with 125I hCG, (b) the cAMP accumulation was prevented in a dose dependent manner reaching a minimal of 1.1 pM at 50 microM, compared with 3.5 pM in hCG (10 ng/ml) stimulated cells. The drug RN-IV B at a concentration of 100 microM, which failed to prevent conversion of exogenous pregnenolone or progesterone to testosterone, otherwise caused complete inhibition of testosterone production in hCG stimulated cells. Mastoparan also inhibited testosterone production in hCG stimulated cells in a dose dependent manner.(ABSTRACT TRUNCATED AT 250 WORDS)
