Abstract
Polycystic Ovarian Syndrome (PCOS) is a prevalent metabolic and hormonal disorder affecting women of reproductive age. Limited data exists on Syrian women's PCOS awareness and health behaviors. This study aimed to gauge PCOS prevalence, knowledge, awareness, and health-related practices among Syrian women. A cross-sectional online survey was conducted from 11 February to 27 October 2022, targeting Syrian women aged 18-45. Collaborators from specific medical universities distributed a questionnaire adapted from a Malaysian paper through social media platforms. Out of 1840 surveyed Syrian women, 64.2% were aged 21-29, and 69.6% held bachelor's degrees. Those with a bachelor's degree exhibited the highest mean knowledge score (12.86), and women previously diagnosed with PCOS had a higher mean knowledge score (13.74) than those without. Approximately 27.4% were confirmed PCOS cases, and 38.9% had possible cases. Women with PCOS were 3.41 times more likely to possess knowledge about the condition. The findings suggest a moderate level of PCOS knowledge and health-related practices among Syrian women, emphasizing the need for increased awareness. Consistent local PCOS screening programs, in collaboration with obstetrics and gynecology professionals, are crucial for improving understanding and clinical symptom recognition of this condition among Syrian women.

Abstract
Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that affects a substantial percentage of women, estimated at around 9-21%. This condition can lead to anovulatory infertility in women of childbearing age and is often accompanied by various metabolic disturbances, including hyperandrogenism, insulin resistance, obesity, type-2 diabetes, and elevated cholesterol levels. The development of PCOS is influenced by a combination of epigenetic alterations, genetic mutations, and changes in the expression of non-coding RNAs, particularly microRNAs (miRNAs). MicroRNAs, commonly referred to as non-coding RNAs, are approximately 22 nucleotides in length and primarily function in post-transcriptional gene regulation, facilitating mRNA degradation and repressing translation. Their dynamic expression in different cells and tissues contributes to the regulation of various biological and cellular pathways. As a result, they have become pivotal biomarkers for various diseases, including PCOS, demonstrating intricate associations with diverse health conditions. The aberrant expression of miRNAs has been detected in the serum of women with PCOS, with overexpression and dysregulation of these miRNAs playing a central role in the atypical expression of endocrine hormones linked to PCOS. This review takes a comprehensive approach to explore the upregulation and downregulation of various miRNAs present in ovarian follicular cells, granulosa cells, and theca cells of women diagnosed with PCOS. Furthermore, it discusses the potential for a theragnostic approach using miRNAs to better understand and manage PCOS.

Abstract
Vitamin D receptor (VDR) gene is implicated in hypertension vulnerability due to its role in regulating the renin-angiotensin system (RAS) and blood pressure. In this case-control study, a carefully selected cohort of 111 hypertensive individuals and 100 healthy controls underwent serum analysis using HPLC to measure 25-hydroxy vitamin D levels. Polymorphic variations in the VDR gene were detected and characterized using the PCR-RFLP method. At first, lower 25-hydroxy vitamin D levels were observed in hypertensive individuals compared to controls (p<0.001). The genotype frequency of the VDR gene TaqI showed no significant difference between cases and controls (p>0.05). Similarly, no significant difference was found in the VDR gene BsmI genotype frequency between hypertensive patients and controls (p>0.05). However, a statistically significant distinction was observed in the VDR gene FokI genotype frequency between cases and controls (p<0.01). The odds ratios for FokI genotypes (CC, CT, TT, and CT+TT) were 1.0, 0.590, 1.566, and 0.963, respectively. Furthermore, serum 25-hydroxy vitamin D levels were significantly higher in control subjects compared to hypertensive patients across all genotypes of VDR (p<0.001). Hypertensive patients, excluding those with the FokI VDR gene CC genotype, exhibited significantly higher systolic blood pressure levels compared to the control group (p<0.05). Similarly, hypertensive subjects displayed elevated diastolic blood pressure levels compared to the control group (p<0.001). Overall, the results suggest the presence of a potential inverse correlation between serum 25-hydroxy vitamin D levels and hypertension. The association analysis conducted indicated that there is no significant association between TaqI and bsmI genotypic variants and the risk of developing hypertension. However, it was observed that VDR gene polymorphisms do have a clear association with hypertension susceptibility, as evidenced by the significantly higher occurrence of FokI genotypic variants in hypertensive patients. Our study therefore introduces the possibility of utilizing 25-hydroxy vitamin D deficiency and VDR gene polymorphisms as a biomarker for hypertension.

Abstract
Despite the advancements in cancer therapies during the past few years, chemo/photo resistance, severe toxic effects, recurrence of metastatic tumors, and non-selective targeting remain incomprehensible. Thus, much effort has been spent exploring natural anticancer compounds endowed with biosafety and high effectiveness in cancer prevention and therapy. Gambogic acid (GA) is a promising natural compound in cancer therapy. It is the major xanthone component of the dry resin extracted from the Garcinia hanburyi Hook. f. tree. GA has significant antiproliferative effects on different types of cancer, and it exerts its anticancer activities through various pathways. Nonetheless, the clinical translation of GA has been hampered, partly due to its water insolubility, low bioavailability, poor pharmacokinetics, rapid plasma clearance, early degradation in blood circulation, and detrimental vascular irritation. Lately, procedures have been invented demonstrating the ability of nanoparticles to overcome the challenges associated with the clinical use of natural compounds both in vitro and in vivo. This review sheds light on the recent emerging trends for the nanodelivery of GA to cancer cells. To the best of our knowledge, no similar recent review described the different nanoformulations designed to improve the anticancer therapeutic activity and targeting ability of GA.

Abstract
The host immune system status remains an unresolved mystery among several malignancies. An immune-compromised state or smart immune-surveillance tactics orchestrated by cancer cells are the primary cause of cancer invasion and metastasis. Taking a closer look at the tumour-immune microenvironment, a complex network and crosstalk between infiltrating immune cells and cancer cells mediated by cytokines, chemokines, exosomal mediators and shed ligands are present. Cytokines such as interleukins can influence all components of the tumour microenvironment (TME), consequently promoting or suppressing tumour invasion based on their secreting source. Interleukin-10 (IL-10) is an interlocked cytokine that has been associated with several types of malignancies and proved to have paradoxical effects. IL-10 has multiple functions on cellular and non-cellular components within the TME. In this review, the authors shed the light on the regulatory role of IL-10 in the TME of several malignant contexts. Moreover, detailed epigenomic and pharmacogenomic approaches for the regulation of IL-10 were presented and discussed.

Abstract
Numerous research studies have investigated the relationship between ABO and Rhesus (Rh) blood groups and the risk of various cancers, yielding diverse findings. While these blood groups have been established as prognostic factors in some cancers, their relevance to colorectal cancer (CRC) remains uncertain. This research aims to determine the link between CRC and the ABO and Rh blood groups and explore any potential implications for disease survival. A hospital-based prospective observational study was conducted from March 2019 to March 2022 at the Sher-I-Kashmir Institute of Medical Sciences in Srinagar, India. A total of 246 patients with confirmed colorectal cancer were enrolled in the study. Our study observed that blood type B (33.74%) and Rh-positive (91.87%) blood types were the most prevalent, surpassing other blood groups. No statistically significant associations were identified between the blood groups and the studied xenobiotic-metabolizing enzyme gene variants. The study observed a heightened risk of CRC in patients with advanced cancer stages and lymphovascular invasion (P-value < .05). On follow-up, there were no statistically significant differences in 3-year survival rates observed between ABO and Rh blood groups. This study's findings suggest that ABO and Rh blood groups are not associated with the risk of CRC or overall survival among CRC patients. Further clinical studies are needed to establish the precise relationship between blood groups and CRC risks, as well as their implications for the prognosis of CRC patients.

Abstract
Endometrial cancer (EC), the most common adenocarcinoma, represents 90% of uterine cancer in women with an increased incidence of occurrence attributed to age, obesity, hypertension, and hypoestrogenism. Being the most common gynecological malignancy in women, it shows a relation with the activation of different components of the renin-angiotensin system (RAS), which is predominantly involved in maintaining blood pressure, salt, water, and aldosterone secretion, thereby playing a significant role in the etiology of hypertension. The components of the RAS, i.e., ACE-I, ACE-II, AT1R, AT2R, and Pro(renin) receptor, are widely expressed in both glandular and stromal cells of the endometrium, with varying levels throughout the different phases of the menstrual cycle. This causes the endometrial RAS to implicate angiogenesis, neovascularization, and cell proliferation. Thus, dysfunctioning of the endometrial RAS could predispose the growth and spread of EC. Interestingly, the increased expression of AngII, AGTR1, and AGTR2 showed advancement in the stages and progression of EC via the prorenin/ATP6AP2 and AngII/AGTR1 pathway. Therefore, this review corresponds to unraveling the relationship between the progression and development of endometrial cancer with the dysfunction in the expression of various components associated with RAS in maintaining blood pressure.

Abstract
Introduction and importance The left renal vein (LRV) is affected by a venous compression syndrome called Nutcracker syndrome (NCS). This syndrome is characterized by extrinsic compression of the LRV, which usually occurs between aorta and superior mesenteric artery. It is a rare and under-diagnosed condition, more prevalent in females and that, if left untreated, can lead to severe problems. There are no clear guidelines regarding management. Therefore, the authors report this rare case and its symptoms in male patient and they display current management options. Case presentation NCS was observed during computer tomography in a male patient presented with persistent left flank pain and associated haematuria. Ultrasound for left scrotum demonstrated left moderate-sized varicocele. The left varicocele testis unit was 1.6 mm and during the Valsalva manoeuvre in the supine position the testis unit was 2 mm. LRV compression between abdominal aorta and superior mesenteric artery was identified by computer tomography imaging and therefore, diagnosis of NCS was confirmed. Clinical discussion The actual prevalence is unclear, and incidence rates have been observed to fluctuate among age group and more prevalent in women. Main symptoms include haematuria, left flank discomfort, varicocele in men, proteinuria and anaemia. Depending on severity of symptoms, management might range from conservative care to surgery. Conclusion This treatment strategy was effective in reducing the symptoms of the patients. In young patients, conservative treatment is advised for a fair amount of time. However, more studies on how much the authors should wait before considering surgery is important.

Abstract
Forkhead Box M1 (FOXM1)-a key cell cycle regulator is a member of the Forkhead transcription factor family. It plays a key role in embryogenesis and cell proliferation and has been strongly linked to various solid tumors. We sought to understand the regulation of FOXM1 in colorectal cancer (CRC), as well as if and to what extent other clinicopathological characteristics are associated with FOXM1. The investigation comprised 98 CRC samples and normal tissues (controls). All colon cancer patients had a colonoscopy and targeted biopsy. All rectal cancer patients had a CT and MRI. Real-time PCR, Immunohistochemistry, and Western blotting were used to evaluate FOXM1 expression, and the findings were analyzed using SPSS (v.26). FOXM1 mRNA and protein expression were substantially upregulated in tumor tissues, with the majority of these proteins localized in nucleo-cytoplasm. Elevated protein levels of FOXM1 were strongly correlated with lower education level, larger tumor size, lymph node status, lymphovascular invasion (LVI), perineural invasion (PNI), lymph node metastasis (LNM), tumor invasion depth (subserosal and serosal invasion), late stage (III and IV), localization (nucleo-cytoplasmic), intensity (strong) and recurrence. Based on survival analysis, FOXM1 overexpression and nucleo-cytoplasmic localization were associated with shorter disease-free survival while stage and PNI were linked to poorer overall and disease-free survival. According to the results of the Cox regression analysis, stage and PNI were significant predictors of prognosis in CRC patients. FOXM1 expression was elevated in CRC and was linked to reduced disease-free survival. These findings support prior reports and hence FOXM1 can be an important prognostic marker for CRC and a promising therapeutic target. Additionally, we found a link between poor disease-free survival and FOXM1's nucleo-cytoplasmic localization. However, since the sample size of this study was small, further research is needed to validate our findings.

Abstract
Alzheimer's disease (AD) and brain tumors are debilitating neurological conditions that pose significant challenges in current medical practices. Existing treatment options for AD primarily focus on symptom management, and brain tumors often require aggressive therapeutic approaches. Novel disease-modifying strategies and therapeutic agents are urgently needed to address the underlying causes of AD pathogenesis and improve brain tumor management. In recent years, nanoparticles (NPs) have shown promise as valuable tools in diagnosing and managing various brain disorders, including AD. Among these, carbon nanotubes (CNTs) have garnered attention for their unique properties and biomedical potential. Their ability to cross the blood-brain barrier (BBB) with ease opens up new possibilities for targeted drug delivery and neuroprotection. This literature review aims to explore the versatile nature of CNTs, which can be functionalized with various biomolecules or substances due to their sp2 hybridization. This adaptability enables them to specifically target cells and deliver medications under specific environmental conditions. Moreover, CNTs possess an exceptional capacity to penetrate cell membranes, making them valuable tools in the treatment of AD and brain tumors. By delving into the role of CNTs in biomedicine, this review sheds light on their potential in managing AD, offering a glimpse of hope for effective disease-modifying options. Understanding the mechanisms of CNTs' action and their capabilities in targeting and delivering medication to affected cells will pave the way for innovative therapeutic strategies that can improve the lives of those afflicted with these devastating neurological conditions. The exploration of CNTs as a dual therapeutic arsenal for both brain tumors and Alzheimer's disease holds great promise and may usher in a new era of effective treatment strategies for these challenging conditions.

Abstract
BACKGROUND Ovarian cancer is the second most prevalent malignancy in women over 40, especially in low-income nations. For every 100,000 women in Syria, 473 new cases of ovarian cancer are diagnosed. This study aims to investigate the knowledge of ovarian cancer symptoms among Syrian women and determine the factors associated with good knowledge. METHODS An online cross-sectional was performed between July 29 and August 17, 2022. The inquired participants in the study were Syrian females above 18 years. The questionnaire consists of 41 questions organized into three sections: sociodemographic information, Confidence in recognizing ovarian cancer symptoms, and women's Awareness of the symptoms of ovarian cancer. RESULTS This research included 557 Syrian women, and the average age was 23. Only 20.5% of involved women demonstrated a good knowledge of the symptoms of ovarian cancer. The participants who agreed that abdominal pain and pelvic pain are ovarian cancer symptoms formed (36.8%), and (63.9%), respectively. Regarding the additional presenting symptoms of ovarian cancer, "extreme generalized fatigue" was the most often reported symptom (66.1%). Divorced women showed greater knowledge scores than other marital status groups (7.13 ± 3.31, P-value<0.05), while public sector participants scored higher than other occupational groups (6.38 ± 2.5, P-value<0.05). CONCLUSION Our findings indicate that Syrian females have inadequate knowledge regarding ovarian cancer symptoms. More ovarian cancer awareness programs for Syrian women of all ages are needed to increase the early identification of this illness.

Abstract
BACKGROUND This study aims to investigate the knowledge of Syrian women about breast cancer risk factors, warning signals, and barriers. Breast cancer is the most common cancer worldwide and the leading cause of cancer death among women. It develops when cells in the breast tissue grow uncontrollably, forming a tumor that can spread to other parts of the body. MATERIALS AND METHODS This survey was conducted online from September 3 to September 27, 2022, and focused on Syrian women over the age of 18. It was divided into two sections, one focusing on sociodemographic characteristics and the other on breast cancer risk factors, warning signals, and barriers. RESULTS This study found that the majority of the 1305 participants had inadequate knowledge of breast cancer risk factors, warning signs, and barriers. Those with higher levels of education, such as Ph.D. students, had the highest overall scores. The sample was mostly made up of housewives, married women, and women with moderate monthly incomes. CONCLUSION This research found that Syrian women have inadequate knowledge about breast cancer, including risk factors, warning signs, and barriers. To reduce mortality rates, increase survival rates, and improve early diagnosis, local health organizations should provide awareness courses to emphasize the importance of annual breast exams.

Abstract
BACKGROUND Suppressor of fused (SuFu) is a tumor-suppressor gene that regulates hedgehog signaling. Its involvement in some malignancies is broadly accepted. However, its association with colorectal cancer (CRC) pathogenesis is not clear. Likewise, no study has clearly associated blood-based inflammatory biomarkers with cancer diagnosis/prognosis as yet. AIM Our goal was to look at SuFu expression levels in CRC patients and its relationship with other clinicopathological factors. Additionally, we looked into the function of a few blood-based biomarkers in CRC and whether or not a combined strategy at the genetic and clinical levels can be applied in CRC. METHODS The investigation included 98 histopathologically confirmed CRC samples and adjacent normal tissues (controls). A colonoscopy was followed by a targeted biopsy for each suspected colon cancer patient. A CT scan and MRI were also performed on every patient with rectal cancer. Real-time polymerase chain reaction and immunohistochemistry (IHC) were used for assessment. A Beckman Coulter DxH900 was used to examine blood parameters. A Beckman Coulter DxI800 was used to identify pretreatment carcinoma embryonic antigens (CEA) and carbohydrate antigens (CA 19-9) in CRC patients. RESULTS The expression of SuFu was associated with gender, education, passive smoking, tumor grade, perineural invasion (PNI), lymph node metastasis (LNM), node status, stage, vital status, and recurrence (p < 0.05). In the combined analysis, the areas under the curve produced by the platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and red cell distribution width (RDW) were the greatest (AUCRDW+PLR+NLR = 0.91, 95% CI: 0.86-0.93, p < 0.05). Furthermore, the most severe pathological features were linked to RDW, PLR, NLR, and HPR. SuFu expression, node status, LNM, PNI, and stage all had significant correlations with OS and DFS rates in IHC-based univariate survival analysis (p < 0.05). According to the Cox regression, CA-19.9 had a strong independent predictive link with 3-year DFS (p < 0.05). CONCLUSION In CRC, SuFu was downregulated both transcriptionally and translationally, was primarily nucleo-cytoplasmic, and was expressed less in high-grade tumors. In addition, SuFu was linked to a poor overall and disease-free survival rate. It may be possible to use SuFu as a therapeutic target for CRC in the future. However, SuFu expression had no effect on RDW, PLR, NLR, or HPR serum levels.

Abstract
Colorectal cancer is a sporadic, hereditary, or familial based disease in its origin, caused due to diverse set of mutations in large intestinal epithelial cells. Colorectal cancer (CRC) is a common and deadly disease that accounts for the 4th worldwide highly variable malignancy. For the early detection of CRC, the most common predictive biomarker found endogenously are KRAS and ctDNA/cfDNA along with SEPT9 methylated DNA. Early detection and screening for CRC are necessary and multiple methods can be employed to screen and perform early diagnosis of CRC. Colonoscopy, an invasive method is most prevalent for diagnosing CRC or confirming the positive result as compared to other screening methods whereas several non-invasive techniques such as molecular analysis of breath, urine, blood, and stool can also be performed for early detection. Interestingly, widely used medicines known as non-steroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation have reported chemopreventive impact on gastrointestinal malignancies, especially CRC in several epidemiological and preclinical types of research. NSAID acts by inhibiting two cyclooxygenase enzymes, thereby preventing the synthesis of prostaglandins (PGs) and causing NSAID-induced apoptosis and growth inhibition in CRC cells. This review paper majorly focuses on the diversity of natural and synthetic biomarkers and various techniques for the early detection of CRC. An approach toward current advancement in CRC detection techniques and the role of NSAIDs in CRC chemoprevention has been explored systematically. Several prominent governing mechanisms of the anti-cancer effects of NSAIDs and their synergistic effect with statins for an effective chemopreventive measure have also been discussed in this review paper.

Abstract
BACKGROUND Connective tissue growth factor (CTGF) is a mediator of transforming growth factor-beta signaling and plays a key role in connective tissue remodeling, inflammatory processes and fibrosis in various illnesses including cancer.
AIM To investigate the role of CTGF in colorectal cancer (CRC) progression and to compare the CTGF expression with different clinicopathological parameters.
METHODS Real-time polymerase chain reaction, immunohistochemistry and Western blotting was performed to evaluate the CTGF expression and the results were statistically analyzed against the clinicopathological variables of patient data using STATA software version 16.
RESULTS CTGF expression levels in tumor specimens were significantly higher than their paired normal specimens. The higher protein expression levels showed a significant association with smoking, staging, tumor grade, invasion depth, necrosis of tumor tissue, and both lymphovascular and perineural invasion. As per the cox regression model and classification tree analysis, tumor-node-metastasis stage and perineural invasion were important predictors for CTGF expression and prognosis of CRC patients. Survival analysis indicated that CTGF overexpression was associated with poorer overall and disease-free survival.
CONCLUSION Expression of CTGF was increased in CRC and was linked with poor overall and disease-free survival of CRC patients. These findings support prior observations and thus CTGF may be a possible prognostic marker in CRC.

Abstract
The effect of garlic supplementation on zootechnical performance and hepato-renal functions of rabbits exposed to experimental nitrate poisoning was evaluated. Adult male 6-8 week-old albino rabbits (n= 24) were randomly divided into four groups (A - D) and subjected to nitrate intoxication through the oral administration of sodium nitrate solution at 2 ml/kg bodyweight per day for 40 days. Group A was a control that received no treatment except sodium nitrate. Rabbits in groups B and C were treated with 1% methylene blue solution (2 mg/kg bodyweight per day) and aqueous garlic extract (500 mg/kg bodyweight per day) through intraperitoneal and oral routes, respectively. Rabbits in group D were treated with both 1% methylene blue solution (2 mg/kg bodyweight per day, intraperitoneally) and aqueous garlic extract (500 mg/kg bodyweight per day, orally). On completion of the treatment period, the groups were compared in growth performance, biochemical profile and histopathological changes of hepato-renal tissues. Although the total feed consumption of the groups remained comparable, Group C showed relatively better weight gain and feed conversion ratio (FCR). Likewise, garlic extract significantly increased the serum bilirubin concentration and reduced the level of other biochemical attributes in comparison with control animals. The hepatic and renal tissues of Groups C and D remained normal, whereas those of the control group exhibited distinct histopathological alterations. It was concluded that garlic supplementation ameliorated the deleterious effects of nitrate intoxication on production performance and hepato-renal functions of rabbits.

Abstract
Background
Transanal total mesorectal excision (TaTME) for rectal cancer has emerged as an alternative to the traditional abdominal approach. However, concerns have been raised about local recurrence. The aim of this study was to evaluate local recurrence after TaTME. Secondary aims included postoperative mortality, anastomotic leak and stoma rates.
Methods
Data on all patients who underwent TaTME were recorded and compared with those from national cohorts in the Norwegian Colorectal Cancer Registry (NCCR) and the Norwegian Registry for Gastrointestinal Surgery (NoRGast). Kaplan–Meier estimates were used to compare local recurrence.

In Norway, 157 patients underwent TaTME for rectal cancer between October 2014 and October 2018. Three of seven hospitals abandoned TaTME after a total of five procedures. The local recurrence rate was 12 of 157 (7·6 per cent); eight local recurrences were multifocal or extensive. The estimated local recurrence rate at 2·4 years was 11·6 (95 per cent c.i. 6·6 to 19·9) per cent after TaTME compared with 2·4 (1·4 to 4·3) per cent in the NCCR (P < 0·001). The adjusted hazard ratio was 6·71 (95 per cent c.i. 2·94 to 15·32). Anastomotic leaks resulting in reoperation occurred in 8·4 per cent of patients in the TaTME cohort compared with 4·5 per cent in NoRGast (P = 0·047). Fifty-six patients (35·7 per cent) had a stoma at latest follow-up; 39 (24·8 per cent) were permanent.
Conclusion
Anastomotic leak rates after TaTME were higher than national rates; local recurrence rates and growth patterns were unfavourable.

Abstract
In advanced chronic kidney disease (CKD), hypocalcemia, high levels of advanced glycation end products (AGEs), and parathyroid hormone (PTH) coexist and are considered to play a role in the development of chronic vasculopathies. The aim of the present study was to evaluate the impact of a CKD-like environment on cultured endothelial cell (EC) functions and to assess the impact of calcitriol on the expression of parameters such as endothelial nitric oxide synthase (eNOS), receptor of AGEs (RAGE), interleukin 6 (IL-6) and nuclear factor kappa B (NFκB). Human umbilical vein cord endothelial cells (HUVEC) were grown in medium containing low Ca(2+) concentration stimulated with AGE-HSA and PTH and treated with calcitriol for additional incubation. mRNA expression was established by reverse transcriptase-PCR, protein expression by Western blot analysis, IL-6 secretion by ELISA, NOS activity by conversion of [(14)C]arginine to [(14)C]citrulline and DNA-binding activity of NFκB-p65 assayed colorimetrically in nuclear extracts. The CKD-like environment characterized by the association of low Ca(2+) and high levels of AGEs and PTH, depressed eNOS system activity and enhanced RAGE and IL-6 expression/secretion. DNA-binding activity of nuclear NFκB-p65 was increased and the expression of IκBα decreased. Addition of calcitriol normalized the expression, secretion and activity of eNOS, RAGE and IL-6. The enhanced NFκB activity was also counteracted probably due to the increased IκBα expression. The effect of CKD-like environment on EC may partly explain the increased vasculopathies in CKD patients, in contrast to calcitriol, which suggests a vascular protective action.

Abstract
BACKGROUND We showed previously that parathyroid hormone (PTH) may stimulate the endothelial expression of pro-atherosclerotic and pro-inflammatory markers. Considering the impact of PTH on vasculature, we decided to evaluate its effect on mRNA and intra-cellular protein expressions of endothelial vascular endothelial growth factor (VEGF) taking into account that VEGF may play a role in the pathogenesis of endothelial dysfunctions. MATERIALS AND METHODS Human umbilical vein cords endothelial cells (HUVEC) were stimulated for 24 h with 10(-12)-10(-10) mol L(-1) PTH. The VEGF-165 mRNA expression (critical in stimulating endothelial cell proliferation) was evaluated by RT/PCR and the intra-cellular VEGF protein expression by flow cytometry. The pathways by which PTH may have an effect on VEGF expression were also evaluated. RESULTS PTH (10(-10) mol L(-1)) significantly increased VEGF-165 mRNA expression (P < 0.05). The addition of 50 nmol L(-1) protein kinase C (PKC) and 10 micromol L(-1) protein kinase A (PKA) inhibitors significantly reduced the VEGF-165 mRNA expression (P = 0.01). We also examined whether nitric oxide (NO) may be involved in the PTH-induced stimulation of VEGF-165 expression. Pre-treatment of the cells with 200 micromol L-nitro arginine methyl ester (L-NAME, NO synthase inhibitor) was found to inhibit VEGF-165 mRNA expression (P = 0.006). VEGF protein could not be detected in the medium of HUVEC but it was present in the cell cytoplasm. PTH had no significant effect on cytoplasmatic VEGF protein expression. CONCLUSION The stimulatory effect of PTH on endothelial VEGF-165 mRNA expression is partly through PKC and PKA pathways and is also NO dependent.

Abstract
BACKGROUND Disturbances in vitamin D(3) metabolism are associated with an increased cardiovascular morbidity and mortality. The aim of this study was to assess the effects of calcitriol, the active metabolite of vitamin D3, on pro-atherosclerotic parameters in human umbilical vein cord endothelial cells (HUVEC). MATERIALS AND METHODS Calcitriol at 10(-10) and/or 10(-9) mol L(-1) was given to cultured HUVEC which were either non-stimulated or lipopolysaccharide (LPS) stimulated. Inter cellular adhesion molecule-1 and platelet-endothelial cell adhesion molecule-1, were determined by flow cytometry analysis. The receptor of advanced glycation end product (RAGE) and interleukin-6 (IL-6) mRNA expressions by RT-PCR and IL-6 secretion by enzyme-linked immunosorbent assay (ELISA). Nuclear p65 DNA-binding activity was measured by transcription factor assay kit and the inhibitor-kappaBalpha (IkappaBalpha), phosphorylated-IkappaBalpha (P-IkappaBalpha) and phosphorylated-p38 mitogen-activated protein kinase (MAPK) protein levels were determined by Western blot. Results Calcitriol decreased the adhesion molecules expression, as well as the LPS-induced mRNA expressions of RAGE and IL-6 and LPS induced IL-6 secretion. Furthermore, the LPS induced nuclear factor kappaB (NFkappaB)-p65 DNA-binding activity was also decreased by calcitriol. IkappaBalpha levels were increased and p-IkappaBalpha levels decreased after calcitriol treatment. The increased levels of activated p38 MAPK after LPS treatment were also decreased due to pre-incubation with calcitriol. CONCLUSIONS The decreased NFkappaB and p38 activities followed by calcitriol treatment may explain the anti-inflammatory/atherosclerotic properties of calcitriol that were observed previously and were emphasized in this study, demonstrating the inhibitory effect of calcitriol on the pro-inflammatory parameters: adhesion molecules, RAGE and IL-6.

Abstract
BACKGROUND Advanced glycation end-products (AGEs) are elevated in the sera of diabetic patients. The latter are prone to severe bacterial infections. Advanced glycation end-products have been shown to modulate immune competent cell activities. In this study we examined the in vitro effect of advanced glycation end-products on superoxide anion generation by human polymorphonuclear leukocytes. MATERIALS AND METHODS Advanced glycation end-products were prepared by incubation of bovine serum albumin (BSA) with glucose for 90 days. Superoxide production was measured as the superoxide dismutase-inhibitable reduction of ferricytochrome c. The effect of advanced glycation end-products on superoxide production was evaluated in both baseline (nonstimulated) and stimulated (by either formyl-methionyl-leucyl-phenylalanine, or phorbol-myristate-acetate) polymorphonuclear leukocytes. RESULTS The baseline superoxide production of polymorphonuclear leukocytes was significantly increased by advanced glycation end-products in a dose-dependent manner. In contrast, in stimulated polymorphonuclear leukocytes advanced glycation end-products significantly inhibited superoxide production, again in a dose-dependent manner. This inhibitory effect of advanced glycation end-products was observed after dialyzing AGE-BSA, thereby eliminating the possible influence of reactive carbohydrates. No modification of superoxide production was seen with BSA and only a mild inhibitory effect of glucose at high concentrations. CONCLUSIONS Advanced glycation end-products depress superoxide production by stimulated polymorphonuclear leukocytes. As superoxide plays an essential role in bactericidal activity, this polymorphonuclear leukocyte dysfunction may be a contributory factor to the increased prevalence and severity of bacterial infection seen in diabetic patients.

Abstract
OBJECTIVE To evaluate the effect of advanced glycation end-products (AGEs) and the inhibitor of their formation, aminoguanidine, on tumor necrosis factor-alpha (TNFalpha) production (as a functional marker) by rat peritoneal macrophages (PMphi). DESIGN Charles River rats underwent a daily intraperitoneal injection of peritoneal dialysis solution [(PDS), 4.25 g/dL dextrose; Dialine, Travenol, Ashdod, Israel] for a 2-month period (group E). Another group of rats was subjected to the same protocol with the addition of 25 mg/kg aminoguanidine (group A). Three control groups were utilized: (1) rats that were injected daily with aminoguanidine only (group AO), (2) rats that were injected with Dulbecco's phosphate-buffered saline (group D), and (3) rats in which no intervention was carried out (group C). After 2 months, PMphi were isolated from rat peritoneal effluent and their TNFalpha production measured by ELISA in cell-free culture supernatants, in both the basal state and after 24-hour stimulation with lipopolysaccharide (LPS). The concentrations of AGEs in peritoneal effluent were assayed and correlated to TNFalpha levels. PMphi obtained from normal rats were then incubated for 24 hours with (1) the peritoneal effluent of each of the above respective groups, with or without LPS; (2) increasing concentrations of AGEs (0-250 microg/mL); and (3) increasing concentrations of aminoguanidine (0-7.5 mg/mL), and TNFalpha secretion again determined. RESULTS After 2 months of daily intraperitoneal injection of PDS, in the basal state, TNFalpha production was significantly higher in PMphi isolated from the peritoneal effluent groups (groups E, A, and AO) compared to controls (group C). Following LPS stimulation, a further increase in TNFalpha secretion was seen, with a significantly greater response in group AO versus groups E, A, and D. Effluent AGEs were markedly elevated only in group E. No correlation was found between TNFalpha secretion by these PMphi and the concentration of AGEs. On incubation with the respective peritoneal effluents (groups E, A, and AO), in both the basal and stimulated state, TNFalpha production by PMphi from normal rats was significantly enhanced compared to group C. Incubation with increasing concentrations of AGEs or aminoguanidine resulted in an increase of TNFalpha secretion by these PMphi. CONCLUSIONS Following intermittent intraperitoneal administration of glucose-based PDS, rat PMphi are chronically activated, as evidenced by increased basal TNFalpha secretion. The peritoneal effluent of such treated animals is capable of stimulating TNFalpha production by normal rat PMphi. These data suggest that glucose-based PDS acts as a primer of PMphi, which retain their ability to further stimulation by LPS. Although, in vitro, AGEs promote TNFalpha secretion by normal rat PMphi, in vivo, their influence is probably modulated by other factors. Aminoguanidine has a specific inducing effect on rat PMphi, independent of glucose-based PDS.

Abstract
BACKGROUND/AIM Heparin has been shown to be renoprotective in a number of experimental nephropathies. The inflammatory component in the early phase of Adriamycin (ADR) induced nephropathy has been established. A microdose of low molecular weight heparin (Fragmin; F) has been noted to exert immunomodulatory effects independent of its anticoagulant activity. We assessed the effects of microdoses of F on daily proteinuria and glomerular production of tumor necrosis factor alpha (TNF-alpha) and prostaglandins 8 and 15 days after induction of ADR nephropathy. METHODS Following intravenous injection of ADR (7 mg/kg) to Wistar rats weighing 200 +/- 20 g, F 20 microg/day/rat s.c. was administered for 8 and 15 days (groups F8 and F15). The respective control groups (C8 and C15) received normal saline subcutaneously. Proteinuria, serum albumin, and creatinine clearance were evaluated on days 8 and 15. The production of TNF-alpha and prostaglandins from glomerular supernatants was measured by radioimmunoassay on days 8 and 15. RESULTS F significantly reduced proteinuria (mg/day) on day 8: 13.6 +/- 1.2 in F8 versus 40.3 +/- 2.7 in C8 (p = 0.008). The glomerular production of TNF-alpha (pi/ml) was significantly lower on day 8 in rats treated with F: 356 +/- 33 in F8 versus 764 +/- 81 in C8 (p = 0.006). A decrease in the prostaglandin E2/thromboxane B2 ratio was noted in the F group between 8 and 15 days (1.1 in F8 vs. 0.9 in F15, p = 0.005) which principally reflects an increase of thromboxane B2. The antiproteinuric effect of F shown after 8 days was no longer present after 15 days (354 +/- 91 mg/day in F15 vs. 499 +/- 69 mg/day in C15, p = 0.33). The same trend was seen for the glomerular production of TNF-alpha. Light microscopy and immunohistochemistry for interstitial and glomerular macrophages were negative. CONCLUSION The lowering effect of microdoses of F on the proteinuria seen during the early phase of ADR nephropathy may be mediated by a decreased production of glomerular TNF-alpha, supporting the anti-inflammatory action of low molecular weight heparin.

Abstract
OBJECTIVE Glucose-based dialysate induces non enzymatic glycation within the peritoneal cavity. To evaluate the relationship between the formation of advanced glycation end-products (AGEs) and peritoneal transfer for small solutes and macromolecules, we developed a model of simulated peritoneal dialysis (PD) in normal rats. METHODS Male albino rats of the Charles River strain were divided into two sets of 3 groups (15-25 rats in each group). In the experimental (E) group, the rats were intraperitoneally (i.p.) injected daily with a commercially available 4.25% dextrose solution. In the control puncture (CP) group, the peritoneum was punctured daily, but no PD solution infused. In an age-matched control (CC) group, no intervention was given. Two study protocols were used. Protocol A (duration 20 weeks) consisted of a daily i.p. injection of 10 mL PD solution per 100 g body weight. In protocol B, a double volume of PD solution was introduced (20 mL per 100 g body weight). At 9, 16, and 20 weeks in protocol A, and at 9 weeks in protocol B, urea, creatinine, microalbumin [(MAL) measured using specific anti-rat albumin monoclonal antibody], and AGEs (measured by fluorescent assay with excitation at 370 nm and emission at 440 nm) were measured in peritoneal effluent and serum. RESULTS At no time during the study were AGEs detected in serum from any group in either protocol. In both protocols, no differences were found between the control groups (CP, CC) with respect to all parameters. In protocol A, the dialysate-to-plasma ratio (D/P) of urea was significantly higher in the experimental group as compared with the control groups at 9, 16, and 20 weeks [9 weeks: 0.59 +/- 0.03 (E) vs 0.39 +/- 0.02 (CP) vs 0.46 +/- 0.02 (CC), p < 0.0004 and p < 0.002, respectively; 16 weeks: 0.71 +/- 0.08 (E) vs 0.42 +/- 0.01 (CP) vs 0.46 +/- 0.01 (CC), p < 0.0001 and p < 0.02, respectively; 20 weeks: 0.57 +/- 0.03 (E) vs 0.39 +/- 0.01 (CP) vs 0.41 +/- 0.02 (CC), p < 0.002 and p < 0.004, respectively]. At 16 and 20 weeks, dialysate MAL levels were significantly increased in group E [16 weeks: 354.00 +/- 80.35 microg/mL (E) vs 134.75 +/- 14.36 microg/mL (CP) vs 110.69 +/- 7.83 microg/mL (CC), p < 0.04 and p < 0.03, respectively; 20 weeks: 283.17 +/- 14.71 microg/mL (E) vs 105.14 +/- 12.11 microg/mL (CP) vs 135.50 +/- 19.03 microg/mL (CC), p < 0.00001 and p < 0.0001, respectively]. In protocol B, at completion of the study (week 9), D/P urea, effluent MAL, and AGEs were significantly higher in the experimental group as compared with the control groups [D/P: 0.67 +/- 0.04 (E) vs 0.46 +/- 0.07 (CP) vs 0.41 +/- 0.02 (CC), p < 0.0002 and p < 00001, respectively; MAL: 336.8 +/- 63.30 microg/mL (E) vs 125.71 +/- 16.77 microg/mL (CP) vs 119.00 +/- 39.75 microg/mL (CC), p < 0.008 and p < 0.007, respectively; AGEs: 265.77 +/- 33.49 U/mg creatinine (E) vs 163.10 +/- 21.99 U/mg creatinine (CP) vs 83.17 +/- 22.66 U/mg creatinine (CC), p < 0.02 and p < 0.001, respectively]. Peritoneal effluent AGEs were found to be significantly correlated with D/P urea and dialysate MAL (r = 0.42, p < 0.04, and r = 0.7, p = 0.00001, respectively). CONCLUSIONS In situ generation of AGEs constitutes the chief origin of peritoneal AGEs. Advanced glycation end-products affect peritoneal permselectivity for both small and large solutes. The rat model of simulated peritoneal dialysis developed in this experiment provides a reliable method for studying peritoneal AGE formation and effect on peritoneal transfer of small solutes and macromolecules.

Abstract
Immunotherapy with the immunomodulating thymic humoral factor-gamma 2 (THF-gamma 2) octapeptide, combined with 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) chemotherapy, will be used for enhancing host immune response to arrest pulmonary metastases of a B16-F10.9 melanoma tumor. In this experimental model of pulmonary metastasis, the highly metastatic B16-F10.9 melanoma tumor cells (2 x 10(5)) were inoculated into the footpad of mice to form a primary tumor. The tumor-bearing leg was surgically removed on reaching the size of 5.5 mm, which resulted in the appearance of metastases in the lungs of the animals. After tumor excision, mice were treated intraperitoneally with a single dose of BCNU (20 or 35 mg/kg) followed by a series of intraperitoneal THF-gamma 2 injections (1 microgram/0.5 ml/injection). Relative to untreated mice and those receiving chemotherapy alone, the antitumor action of the combined THF-gamma 2 chemoimmunotherapy protocol was significantly augmented according to the following in vivo parameters: (a) decreased postsurgical spontaneous metastatic burden; (b) prolonged survival time; (c) increased resistance to tumor cell challenge; and (d) massive infiltration of lymphocytes, polymorphonuclear cells, and macrophages in the lung tissue. The THF-gamma 2 immunotherapy also prevented a decrease in lymphocyte reactivity, otherwise induced by the tumor/BCNU chemotherapy. THF-gamma 2 immunotherapy resulted in restoration of the response to Lipopolysaccharide mitogenic stimulation and the allogeneic response. Our data suggest that postoperative THF-gamma 2 immunotherapy could be a valuable adjunct to anticancer chemotherapy as a treatment for metastatic arrest of melanoma tumor.

Abstract
Previous research in our laboratories has shown that the immunoregulatory octapeptide, THF-gamma 2, potentiates the efficacy of anticancer chemotherapy in experimental animal models of local plasmacytoma and repairs drug-induced defects in immunocompetence. The highly metastatic, murine D122 lung carcinoma model has been shown to be useful for evaluating the efficacy of experimental antimetastatic therapeutic modalities. The goal of the present study was to determine whether intranasal thymic humoral factor-gamma 2 (THF-gamma 2) immunotherapy, after a single dose of chemotherapy, could inhibit the development of lung metastases, restore immunocompetence, and increase survival in syngeneic C57BL/6 mice bearing highly metastatic Lewis lung carcinoma (D122) solid footpad tumors. Relative to untreated mice and those receiving chemotherapy alone, mice receiving combined chemoimmunotherapy showed the following significant differences: (a) decreased lung metastatic load as assessed by lung weight, (b) prolonged survival time, (c) massive infiltration of lymphoid cells in the lungs, and (d) restoration of impaired immune parameters to normal values in melphalan-treated mice. THF-gamma 2 prevented tumor emboli from colonizing the target tissue, probably by inducing expansion of the lymphoid cell compartment. When used as an adjunct to anticancer chemotherapy, intranasal THF-gamma 2 immunotherapy is a simple and safe treatment modality that seems to be promising for inhibiting lung metastases.

Abstract
In mice bearing immunogenic tumors, adding thymic humoral factor-gamma 2 (THF-gamma 2)1 immunotherapy as an adjunct to anticancer chemotherapeutic regimens not only potentiates the antitumor activity of each drug but also repairs tumor/chemotherapy-induced damage to T-cell populations and functions. The Lewis lung carcinoma (3LL) is a weakly immunogenic, highly metastatic tumor in C57BL/6 mice. To investigate whether the immunoregulatory octapeptide is also effective against a tumor that does not elicit an antitumor immune response, we assessed the effect of combination THF-gamma 2 immunotherapy and chemotherapy in 3LL-bearing mice. The results indicate that THF-gamma 2 combined with either Melphalan or 5-Fluorouracil was more effective in reducing metastatic load than either chemotherapeutic drug alone and was characterized by massive infiltration of lymphatic cells. The combined chemoimmunotherapy treatment also prolonged the survival time in all treated animals and repaired T-cell defects and impaired in vitro cellular immune response parameters, induced either by the tumor or by chemotherapy. THF-gamma 2 immunotherapy reversed the decrease in the number of bone-marrow myeloid colonies (GM-CFU) induced by chemotherapy treatment of tumor-bearing mice, supporting the hypothesis that THF-gamma 2 directly stimulates the proliferation of myeloid stem cells. The overall results imply, that when administered as an adjunct to chemotherapy, THF-gamma 2 immunotherapy is equally effective against immunogenic and nonimmunogenic tumors.

Abstract
A Methanol Extraction Residue (MER) of BCG tubercle bacillus induced cytostatic activity in vitro against the murine tumor-cell lines YAC-1 and MOPC-315 in resident murine peritoneal macrophages isolated from BALB/c mice. The induction of antitumor activity was not associated with increase in release of TNF-alpha. Macrophages from mice hyperimmunized with MER (MER 3x) or from mice injected once with MER in aqueous suspension released more PGE2 following stimulation in vitro with LPS. Macrophages cultured with either MER or MER+LPS prolonged the survival time of mice bearing palpable RPC5 plasmacytoma s.c. tumors.

Abstract
The Nocardia fraction NLD-RB1040 (Nocardia Lysozyme Digest) induced cytostatic activity in vitro against the YAC-1 tumor-cell line, in resident murine peritoneal macrophages isolated from BALB/c mice. The induction of antitumor activity by the Nocardia fraction was not correlated with induced changes in production of TNF alpha, PGE2 or nitrite by human peritoneal macrophages collected from renal patients on Continuous Ambulatory Peritoneal Dialysis (CAPD), or changes in production of TNF a by murine macrophages.

Abstract
Previously reported studies revealed that extensive immunization with the Methanol Extraction Residue (MER) of BCG tubercle bacillus in Incomplete Freund's Adjuvant (IFA) induced marked suppression of T and B cell functions and that immunosuppression was correlated with marked decrease in splenic T-cell population and marked increase in the splenic macrophage population. The purpose of the present work was to determine if extensive immunization with MER in IFA also induced changes in splenic asialo antigen positive (NK) population and in the potential of induction of splenic LAK activity in vitro by recombinant IL-2. By comparison with other test groups, namely mice injected with IFA only, injected once with MER in aqueous suspension and normal, untreated mice, hyperimmunization with MER resulted in marked increase in expression of asialo positive (NK) splenic cells whereas induction of splenic LAK activity by IL-2 was markedly depressed. Splenic macrophages originated from MER hyperimmunized mice had no effect on induction of LAK activity by IL-2 in a normal splenic population.

Abstract
Previously reported studies revealed that extensive immunization with the Methanol Extraction Residue (MER) of BCG tubercle bacillus in Incomplete Freund's Adjuvant (IFA) induced marked suppression of T and B cell functions in vivo and in vitro. The purpose of the present work was to determine whether immunosuppression induced by hyperimmunization with MER is correlated with changes in morphological characteristics and in phenotype pattern of spleen and peritoneal lymphoid cells. Hyperimmunization with MER resulted in a marked increase in the number of spleen cells and in enlargement and granulation of spleen and peritoneal cells. Similar changes in size and granulation were also observed in isolated fractions of splenic T and B cells. Extensive immunization with MER also induced marked decrease in the total number of T cells (Thy 1,2 positive). The decrease in T cells was observed in all three T-cell subsets investigated: Lyt-1, Lyt-2 and L3T4 positive. Although the number of splenic B cells was decreased in samples (10,000 cells), taken from MER hyperimmunized mice, this decrease was compensated by overall increase in the number of spleen cells. The marked decrease in the percentage of splenic T cells was counterbalanced by marked increase in the splenic macrophage population: increase in MAC-1, MAC-2 and MAC-3 positive cells. It is concluded that extensive immunization with MER induces morphological changes in spleen and peritoneal cells, marked decrease in the number of splenic T cells and marked increase of the splenic macrophagic population. It is postulated that these changes are correlated with induction of immunosuppression by a similar procedure of extensive immunization with the agent.

Abstract
Previously reported studies revealed that spleen cells from BALB/c mice immunized against a methanol extraction residue (MER) fraction of tubercle bacilli are defective in the in vitro generation of antibodies to SRBC and in allogeneic responsiveness against C57BL spleen cells. We now show that mice repeatedly immunized with MER also exhibit a depressed capacity to respond to antigenic stimulation in vivo. Thus mice repeatedly injected with MER were impaired in their ability to react to antigenic stimulation by SRBC and by C57BL spleen cells. Impairment in the response to SRBC immunization was expressed at the level of delayed-type hypersensitivity (DTH) as well as of antibody production. The response of MER hyperimmunized mice to contact sensitization with dinitrofluorobenzene (DNFB) was not impaired, but the lymph node cells of DNFB-sensitized animals had a depressed ability to respond to in vitro stimulation by the monovalent hapten dinitrobenzene sulfonate (DNBS). The present findings indicate that extensive exposure to an immunogenic immunomodulating mycobacterial fraction can lead to a depressed responsiveness to unrelated antigenic stimulation.

Abstract
BALB/c mice cured of large MOPC-315 plasmacytomas by melphalan remain deficient in their spleen T-cell functions. This was manifested by impairment of the allogeneic and the antibody responses in vitro to SRBC and in decreased numbers of T-cells including their subsets CD4 and CD8. IL-2 production and specific cytotoxicity against MOPC-315 tumor cells were, on the other hand, maintained. Treatment of these cured mice by in-vivo administration of THF-gamma 2, an octapeptide from calf thymus, repaired these deficits. This was evidenced by in vitro tests with spleen cells which manifested an increased allogeneic response and elevated generation of primary antibody response, restoration of T-cell subpopulations to normal and an enhanced IL-2 production above normal levels. The potential use of THF-gamma 2 as supportive therapy in cancer treatment is suggested.

Abstract
The immunocompetence status of mice bearing MOPC-315 plasmacytoma was determined at various days after tumor inoculation. Changes in T and B-cell functions appeared gradually. The allogeneic response of spleen cells from BALB/c tumor-bearing mice against C57BL spleen cells was impaired from the 4th day after the tumor inoculation (nonpalpable tumor stage). The primary antibody response in vitro against SRBC was depressed at 18 days, and the mitogenic response of splenic cells to PHA and to LPS was depressed at 25 days after the tumor inoculation. T cells taken from day 18 tumor-bearing mice partially suppressed the MLR response of normal splenocytes. Mice bearing large MOPC-315 tumors responded less to SRBC immunization than normal, noninoculated mice. The relative percentage of Lyt 1, Lyt 2 and L3T4 T-cell subsets decreased starting from the 11th day after tumor inoculation.

Abstract
The effect of the thymic hormone, THF-gamma 2, on the immunocompetence of 5-fluorouracil (5-FU)-treated BALB/c mice, bearing MOPC-315 tumor, was examined. Treatment of noninoculated or tumor-bearing mice with THF-gamma 2 after 5-FU injection, resulted in an increase in the antibody response to sheep red blood cells and in the allogeneic response in spleen cell cultures and had no effect on the concanavalin-A-induced interleukin-2 secretion beyond that caused by 5-FU alone. Treatment with either 5-FU alone or 5-FU and THF-gamma 2 resulted in restoration to normal values of Lyt1- and L3T4-positive populations in tumor-bearing mice. THF-gamma 2 prolonged the survival time of mice bearing MOPC-315 tumor beyond that observed in mice treated with 5-FU alone.
