The effects of Ganoderma lucidum (Gl) and Krestin (PSK) extracts on cellular immunocompetence, leukocyte counts and differential count in γ-irradiated mice were investigated in this study. ICR strain male mice were used and randomly divided into five groups. Group A is normal control. Group B, the experimental control, was treated with Gl. Group C, the radiation treatment control, was treated with whole body exposure to 4 Gy γ-irradiation (RT). Group D was treated with RT and Gl. Group E was treated with RT and PSK. The dosage of Gl was 400 mg/day/kg body weight and PSK was 500 mg/day/kg body weight. After irradiation, six mice from each group were sacrificed on day 7 and the other six on day 28. Cellular immunocompetence was measured by means of 3 H -thymidine incorporation with splenic cells stimulated through mitogens such as PHA, Con A and LPS. The results revealed that relative splenic weight in Groups D and E were higher than group C on day 28 after γ-irradiation, Group D was the highest in all the experimental groups. Leukocyte counts were decreased significantly in Groups D and E on day 7, the former was a little higher than the latter. Gl administration showed an increase in the leukocyte count in Group D on day 28. The blastogenic response of splenocytes to PHA and Con A in groups D and E were higher than in Group C on days 7 and 28. We suggested that Gl and PSK were effective in enhancing the recovery of cellular immunocompetence from γ-ray irradiation.

Effects of Ganoderma lucidum (Gl) and Krestin (PSK) extracts on spleen, thymus and splenocytes in γ-irradiated mice were investigated in this study. ICR strain male mice were divided into five groups. Group A was the normal control. Group B, the experimental control, was treated with Gl. Group C, the radiation treatment control, was treated with whole body exposure to 4 Gy γ-irradiation (RT). Group D was treated with RT and Gl. Group E was treated with RT and PSK. The dosage of Gl was 400 mg/day/kg body weight and PSK was 500 mg/day/kg body weight. Our results indicated that the relative thymus weight in groups D and E were higher than group C on day 28 after γ-irradiation. Group D was the highest in all the experimental groups. CD4 and CD8 splenocytes in group D were higher than group C on days 7 and 28. Gl was better than PSK in repairing the damage of subset T-cells in the spleen of γ-irradiated mice.

Radiation protective effects of Gynostemma Pentaphyllum (Gp) were investigated in γ-irradiated mice. Animals were sacrificed on days 5, 15, 25 and 35 after γ-irradiation. GOT, GPT, serum IgG and leukocyte counts were measured. Proliferation of splenocytes stimulated by mitogens, such as PHA, Con A, and LPS were detected and compared. The results showed that all parameters measured in this study were decreased and proliferation of splenocytes stimulated by mitogens were repressed in γ-irradiated mice. Gp helped to recover the decreased leukocyte counts, GOT, GPT and IgG in serum and the proliferation of splenocytes stimulated by PHA, LPS and Con A in the γ-ray irradiated mice.

The effects of moxibustion on cellular immunocompetence of γ-irradiated mice were investigated in this study. A total of 240 male young mice (ICR strain), 6–8 weeks of age, were chosen and divided into three groups. Group A was the normal control. Group B, the experimental control, was treated with 400 rad whole body γ-irradiation. Group C, the experimental group, was treated with moxibustion (MT) after being exposed to γ-irradiation. Six to eight mice from each group were sacrified on days 1, 5, 12, 19, 26 and 33 post-irradiation. The body and splenic weights of mice in each group were measured. The cellular immunocompetence was measured by 3H-thymidine uptake in each experimental mouse. The results revealed that 400 rad of γ-ray irridiation inhibited the increase of body and splenic weights, and exerted a pronounced inhibitory effect on the incorporative rates of 3H-thymidine after being stimulated by mitogens such as PHA, PWM, Con A and LPS in the splenic lymphoid cells. MT seemed to help the recovery of the cellular immunocompetence in the γ-ray irradiated mice.

We have studied the biological effects of the internal exposure to radioactive manganese-56 dioxide (56MnO2), the major radioisotope dust found in soil after atomic bomb explosions. Our previous study of blood chemistry indicated a possible adverse effect of 56MnO2 on the liver. In the present study, we further examined the effects on the liver by determining changes in hepatic gene expressions. Male Wistar rats were exposed to 56MnO2 particles (three groups with the whole-body doses of 41, 90, and 100 mGy), stable MnO2 particles, or external 60Co γ-rays (2 Gy), and were examined together with the non-treated control group on postexposure day 3 and day 61. No histopathological changes were observed in the liver. The mRNA expression of a p53-related gene, the cyclin-dependent kinase inhibitor 1A, increased in 56MnO2 as well as in γ-ray irradiated groups on postexposure day 3 and day 61. The expression of a stress-responsive gene, nuclear factor κB, was also increased by 56MnO2 and γ-rays on postexposure day 3. However, the expression of cytokine genes (interleukin-6 or chemokine ligand 2) or fibrosis-related TGF-β/Smad genes (Tgfb1, Smad3, or Smad4) was not altered by the exposure. Our data demonstrated that the internal exposure to 56MnO2 particles at less than 0.1 Gy significantly affected the short-term gene expressions in the liver in a similar manner with 2 Gy of external γ-irradiation. These changes may be adaptive responses because no changes occurred in cytokine or TGF-β/Smad gene expressions.

This study aimed to evaluate the efficacy of ivermectin, levamisole HCl and albendazole against gastrointestinal nematodes in naturally infected goats of government goat development farm, Sylhet, Bangladesh. The study included 52 black Bengal breed of which 30 were naturally infected and randomly selected 20 on the basis of their weight and egg count. Twenty black Bengal goats of 12-13 month old irrespective of sex infested with gastrointestinal nematodes were selected for this experiment and randomly divided into four equal groups (group A, B, C and D) where each group consisted of 5 goats and goats of group D were kept as control group. One injectable ivermectin (200?gkg-1 body weight, S/C) preparations (Techno Drugs Ltd. Bangladesh) and two solid levamisole HCl, albendazole (7.5 mgkg-1 body weight, orally) preparations (The ACME Laboratories Ltd. and Square Pharmaceuticals Ltd. Bangladesh) were used for positive control of gastrointestinal nematodes as group A, B and C. Goats of group D was kept as control without giving any treatment. Before trials (day 0), total egg count, blood samples and initial body weight were recorded. During the study period the fecal and blood samples were collected directly from rectum and examined on 7th, 14th, 21st and 28th day using McMaster fecal egg counting method. Body weight was recorded on day 28 following the treatments. The results of the comparative efficacies of different anthelmintic of ivermectin was 86.75%, followed by levamisole HCl 85.07% and albendazole 92.81%. McMaster fecal egg counting method discloses the percentage of Haemonchus spp. (15.38%), with Trichostrongylus spp, Strongyloides spp., and Cooperia spp. also present. After treatment with ivermectin, levamisole HCl and albendazole, Total Erythrocyte Count (TEC), Hemoglobin (Hb) content and Packed Cell Volume (PCV) were increased significantly (p<0.01 and p>0.05) in goats but Erythrocyte Sedimentation Rate (ESR) and Total Leukocyte Count (TLC) were decreased significantly (p<0.05 and p>0.01) in all treated goat and body weight was increased significantly (p<0.01) on day 28.International Journal of Natural Sciences (2015), 5(1) 26-34

Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.

Reproductive development in relation to growth and fat deposition was compared in three groups of female rats: a group that was allowed to grow only slowly by requiring them to work hard on a running wheel for their food; a group in which the same slow rate of growth was imposed by restricting their food intake, but without an exercise requirement; and a normally growing, nonexercising, ad libitum-fed, control group. Animals forced to run for their food experienced vaginal opening at a significantly lower body weight than either of the other two groups. The same trend was apparent for the first ovulation, but not significant. Thus the present results suggest that, under some conditions, intense exercise may actually accelerate rather than decelerate reproductive development, at least relative to body weight. With the possible exception of body weight, none of the whole-body parameters measured in this experiment (body weight, growth rate, or amount of fat) were found to be critically related to the first ovulation when all three groups of females were considered as a unit. Thus the present results also argue against some of the current hypotheses, all developed using dietary manipulation, that the onset of fertility is somehow dependent on one of these factors.

This study was conducted under the Department of Physiology and Pharmacology to determine the effects of Neem and Nishyinda leaves supplementation on growth performance and GUT biosis in broilers. A total of 40 day old broiler chicks were divided into four groups A, B, C and D. Group A was considered as control, fed only with commercial broiler ration. Group B supplemented with formulation of 2 gm grinded Neem leaves, Group C with 2 gm grinded Nishyinda leaves and Group D with 1 gm grinded Neem leaves plus 1 gm grinded Nishyinda leaves per liter of water respectively. Observations were recorded for live body weight, weight gain, feed consumption, feed efficiency, hemato-biochemical parameters and GUT biosis specially the parasite of birds in six weeks. Body weights were increased significantly (p<0.05) in all treated groups in respect to the control and highest was recorded in combine Neem plus Nishyinda supplemented groups (Group D). No significant (p>0.05) differences were observed among the groups for PCV and TEC values. Hb content increased and ESR decreased significantly (p<0.05) with combine Neem plus Nishyinda supplemented group (Group D). The serum SGOT and SGPT levels were also decreased with the same kind of supplementation. In treatment group there was significantly decreased of parasitic eggs, but in case of control group no decrease of parasitic eggs. There was no significant pathological change in any internal organs of the broiler of treated groups. Best result was found in the group D. The present study reveals that combine supplementation of Neem plus Nishyinda gives better result over other groups in respect to body weight gain, feed conversion ratio, hemato-biochemical parameter and profitability without making any health hazard of the broilers.

Abstract Graft versus host disease (GvHD) is still a very serious problem in hematopoietic stem cells transplantation which makes searching for new possibilities of its prevention and treatment necessary. Animal models are very useful tools for such research. We present a mouse model of GvHD allowing observation of both acute and chronic phase of the disease. C57Bl/6 mice (H-2b) were transplanted, one day after ablative TBI with 5×106 BM cells and 4×106 or 10×106 splenocytes isolated from allogeneic C3H. He (H-2k) or from syngeneic animals. Sex mismatched transplants were performed and chimerism of transplanted animals was confirmed by detection of sry gene with PCR. As a control group for blood examination after transplantation C3H syngeneic transplantations were performed. After transplantation, mice were weighted and physically examined by looking for changes in skin, posture, physical activity and peripheral blood parameters. Histopathological examination was performed on day +8, +16, +31 in some of the animals. Autopsy was also performed on mice which died during the experiment or which body weight decreased below 65% of the initial weight. We observed a characteristic pattern of physical symptoms of GvHD including weight loss, skin desquamation, hunching and loss of activity, diarrhea. Weight loss to 88.2% of the initial body weight on day +7 was followed by a return to the initial weight (101.1%) on day +14 and then another decrease either strong and leading to the death of the animal or moderate and leading to a long time plateau (the average body weight on days +31, +59 and +101 was 94.4%, 91.7% and 93.6%). On day +7 desquamation of the skin of paws was very well visible and since day +10 gradually intensifying desquamative changes of the skin of whole body were observed - the mean level of changes in the population was highest on days +21 to + 24. Interestingly areas of the skin which were nude before TBI and transplantation were affected earlier (changes were visible on day +7) and more severly than other regions of the skin suggesting that local more intensive damage caused by irradiation can locally aggravate the course of GvHD. The physical symptoms were accompanied with histopathological changes of liver, skin, spleen and gut. Neither physical nor histopathological symptoms of the disease were observed in mice transplanted with syngeneic cells. In fluorocytometric analysis of peripherial blood performed on days +17, +31 and +45 severe lymphopenia was observed. The average number of CD3+CD4+, CD3+CD8+ and B220+ cells was strongly decreased in animals transplanted with allogeneic cells as compared to syngeneic graft recipients. At the same time expression of CD69 activation antigen on CD4+ and CD8+ cells was strongly increased in allograft recipients as compared to syngeneic controls. The course of the disease, including weight loss and skin changes, was generally less severe in the population of mice transplanted with BM + 4×106 splenocytes as compared to BM + 10×106 of splenocytes recipients. The 25th, 50th and 75th percentiles of survival function for both populations were162, 301, 405 and 45, 88, 277 days, respectively.

Abstract Pregnancy and feto-gestational toxicities on exposure to fluoride (F) and its possible amelioration on co-administration with Aloe-vera were studied in pregnant Swiss albino mice. Once the confirmed pregnancy was tested, animals were equally divided into four groups and were given following treatment. Group I was given no treatment and served as Control, Group II and III were administered sodium fluoride, 100 and 300 ppm respectively while group IV was co-administered with sodium fluoride, 300 ppm and Aloe-vera (300mg/kg) daily for 14 days prior to gestation and continued till the 18th day of gestation. Animals were sacrificed `on the 19th day of gestation for prenatal observations. Maternal body weight, the gravid uterine weight, number of corpora lutea in both the ovaries, number of implantations and resorptions, number of live (mature and immature ) male and female fetuses as well as number of dead fetuses were examined in each dam. The treatment continued in another set of animals till the completion of weaning period to observe postnatal changes due to test substances on the mother and pups. Sodium fluoride treated animals showed morphometric and skeletal changes which were more pronounced in the high dose group showing significantly decreased body weight gain in pregnant mothers; and dead/immature fetuses. Morphometric changes included open eyelids, limb defects, wrinkles on whole body, anophthalmias, pulmonary edema, enlarged esophagus and decreased body weight of fetuses and pups. Alizarin prepared skeletal structures of fetuses of such female mice showed delayed ossification or bending in number of bones of skull, thoracic and limb regions. However, concomitant exposure to Sodium Fluoride and Aloe-vera treated animals, there was a marked improvement in all the prenatal and postnatal variables. The study suggests that Sodium fluoride at the high concentrations may be teratogenic while co-administration of Aloe-vera during fluoride exposure might be beneficial in reducing these toxic effects. We thus recommend use of aloe vera as preventive agent or as a complimentary agent during fluoride treatment.
