Methanol poisoning is a hazardous intoxication characterized by visual impairment and formic acidemia. The therapy for methanol poisoning is alcohol dehydrogenase (ADH) inhibitors to prevent formate accumulation. Ranitidine has been considered to be an inhibitor of both gastric alcohol and hepatic aldehyde dehydrogenase enzymes. This study aimed at testing ranitidine as an antidote for methanol acute toxicity and comparing it with ethanol and 4-methyl pyrazole (4-MP). This study was conducted on 48 Sprague-Dawley rats, divided into 6 groups, with 8 rats in each group (one negative control group [C1], two positive control groups [C2, C3] and three test groups [1, 2 and 3]). C2, C3 and all test groups were exposed to nitrous oxide by inhalation, then, C3 group was given methanol (3 g/kg orally). The three test groups 1, 2 and 3 were given ethanol (0.5 g/kg orally), 4-MP (15 mg/kg intraperitoneally) and ranitidine (30 mg/kg intraperitoneally), respectively, 4 hours after giving methanol. Rats were sacrificed and heparinized, cardiac blood samples were collected for blood pH and bicarbonate. Non-heparinized blood samples were collected for formate levels by high performance liquid chromatography. Eye balls were enucleated for histological examination of the retina. Ranitidine corrected metabolic acidosis (p = .025), decreased formate levels (p = .014) and improved the histological findings in the retina induced by acute methanol toxicity.

This research was conducted to study the protective effect of bee honey on the 7,12-dimethylbenz(a)anthracene (DMBA)- induced breast cancer in rat model. The study consisted of three groups: honey group, positive control group (PC), and negative control group (NC) to which the carcinogen was not administered. All rats were fed the diet recommended by the American Institute of Nutrition for growing rats (AIN-93G), with addition of honey (50 g/kg diet) to the honey group. All Rats were fed their diets ad libitum on 12 hours dark/light cycle. At the age of 50 days all rats in the honey and PC groups were gavaged once by the carcinogen DMBA with a dose of 80 mg/kg body Wt. After three weeks of carcinogen administration, rats were palpated weekly to detect any tumor growth. After 18 weeks, all rats were sacrificed. The palpable structures and the mammary glands along with associated lymph nodes were removed and fixed in saline formalin and prepared for histopathological examination. The results revealed that the honey group diet significantly (p < 0.05) reduced the incidence rate of mammary cancer, palpable tumor multiplicity, tumor size and weight compared to the PC group. In conclusion, multi floral honey has a protective effect against DMBA- induced mammary cancer in the initiation, promotion, and progression stages of DMBA-induced mammary carcinogenesis. However, further research is needed to reveal the mechanisms that might have contributed to the preventive effect of honey against mammary cancer.

Abstract Objectives Ocimum gratissimum L. is used in traditional medicine for the treatment of bacterial infections and anaemia. This study was designed to evaluate the effect of O. gratissimum leaf extract on phenylhydrazine (PHZ)-induced anaemia and toxicity in rats. Methods The experimental rats were divided into five groups (A–E) (n=6/sex/group). Each rat in groups B–E was intraperitoneally administered 50 mg/kg of PHZ for two consecutive days. Group A (normal control) did not receive any PHZ, group B (negative control), group C received orally 5 mg/kg ferrous sulphate whereas groups D and E received 200 and 400 mg/kg O. gratissimum leaf extract respectively, for 14 days. Results Red blood cell count, packed cell volume, haemoglobin concentration and high-density lipoprotein increased significantly (p<0.05) whereas low-density lipoprotein and very-low-density lipoprotein decreased in extract-treated groups when compared to the negative control. O. gratissimum (400 mg/kg extract) and standard drug (5 mg/kg ferrous sulphate) significantly (p<0.05) reduced the levels of aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase. Conclusions The results of this study indicate that O. gratissimum leaf extract has a restorative effect on the phenylhydrazine-induced metabolic distortions in the blood, liver, and kidney, and therefore could be used therapeutically as an anti-anaemic tonic.

This study aim was to determine the influence ant nest plant extract (Myrmecodia pendans) on histopathological changeof white rat liver (Rattus novergicus) due to induced with paracetamol toxic dose. This study used 24 male white rats, divided into four groups, negative control group (P0) given placebo, positive control group (P1) given paracetamol dose 250 mg / kg bw for 10 days, P2 given ant nest extract 250 mg / kg bw and paracetamol dose 250 mg / kg bw for 10 days, P3 given ants nest extract 250 mg / kg bw for seven days, then continued by giving paracetamol and ants nest extract with dose 250 mg / kg bw for ten days. After the treatment done, all the rats were dinecropsed. Liver organs were taken and processed for making histopathology preparations. Parameters examined included hemorrhage, congestion, degeneration and necrosis. The data obtained were analyzed statistically by using Kruskal Wallis test followed by Mann Whitney test. Mann Whitney test results for all categories of histopathologic changes in  hemorrhagic, congestion, degeneration, and necrosis between negative control group (P0) and positive control group (P1) were significantly different (P <0.05), between negative control (P0) with P2 and P3 there was no significant difference (P> 0,05). Afterward, between the positive control (P1) and P2 with P3 there was a significant difference (P <0.05). I can be concludedthat the administration of paracetamol dose 250 mg/kg bw for 10 days affects the histopathologic changes of white rat liver. The administration of ant nest plant extracts can reduce the side effects of toxic doses of paracetamol.

Abstract Background and aims: Cardiovascular diseases are widespread and causes many deaths in the world. The concentration of acute phase protein: C-reactive protein (CRP) and fibrinogen will rise dramatically when inflammation happens, which that can be used as an early marker of cardiovascular disease risk. Tempeh gembus contains fiber, unsaturated fatty acids and isoflavones are believed to reduce the inflammatory reaction. The aim of the study was to determinate the effect of tempeh gembus variations to levels of hcCRP and levels of fibrinogen of Sprague Dawley rats with atherogenic diet. Material and methods: This study was quasi-experimental with posttest only randomized control group design using 35 Sprague Dawley mice. The rats were randomized into 5 groups: negative control group given the standard diet, the positive control group given standard diet and atherogenic diet, and three treatment groups were given the standard diet, atherogenic diet and variation of tempeh gembus (tempeh gembus, heated tempeh gembus and tempeh gembus with bromelain enzyme) for 28 days. Serum levels of hsCRP and fibrinogen examined using ELISA (Enzyme-linked Immunosorbent Assay). Results and conclusions: The administration of tempeh gembus with bromelain enzyme is the most effective treatment for hsCRP serum level indicated a significant difference (p=0.028) between the negative control group, positive control group and first group with the third group. Fibrinogen serum levels showed significant differences in all treatment groups (p =0.042), administration of tempeh gembus with bromelain enzyme is the most effective treatment is shown by a significant difference between the negative control group and the positive control group with third group. The administration of tempeh gembus with bromelain enzyme for 28 days can reduce the serum levels of hsCRP and fibrinogen on rats significantly.

This study was conducted to develop Chaguro, a low-cost supplementary food made of chayote (Sechium edule (Jacq.) Swartz) and tuna fish (Thunnus sp.), for diabetes and dyslipidemia diet therapy. In order to find a formula with effective hypoglycaemic and antidyslipidemic properties, dried tuna and chayote were mixed at different ratios: F1 (75% tuna, 25% chayote), F2 (50% tuna, 50% chayote), and F3 (25% tuna, 75% chayote). Thirty male Sprague Dawley rats were assigned into healthy control group or groups induced with streptozotocin-nicotinamide and a high-fat diet. Chaguro was administered 2.7 g/ kgBW/ day using a gavage for 28 days. The administration of all Chaguro formulas improved blood markers compared to the negative control group (p < 0.001). Chaguro F2 lowered fasting blood glucose (97.07±1.18 vs 266.31±5.31), total cholesterol (113.59±2.22 vs 208.78±4.31), triglycerides (89.93±2.51 vs 142.35±2.83), LDL-c (33.87±1.87 vs 87.85±3.34) and increased HDL-c (69,08±1,85 vs 23,91±1,64) level the most compared to the negative control group (p < 0.001). Streptozotocin-induced weight loss was also prevented in all diabetic rats fed with Chaguro, with the bodyweight being similar to that of healthy controls at the end of the intervention (p < 0.001). This study found that Chaguro may be a potential food product to help lower blood glucose and improve lipid profile in diabetes and dyslipidemia.

 Objectives: To analyze the effectiveness of the topical application of a standardized ethanol extract of roselle calyx in the treatment of oral mucous ulceration.Methods: Twelve Sprague Dawley rats were divided into two groups, with oral mucous ulcer being induced in all the rats. The ulcer diameter, reddish color, and the swollen membrane around the ulcer, as well as the inflammation score of the ulcer, were recorded for all animals. The negative control group was treated with aquades, while the positive control group was treated with 0.1% triamcinolone acetonide. The treatment group received the topical application of 7.5% and 15% standardized ethanol extract of roselle calyx twice a day for 3 or 7 days. On the 4th day, six rats were sacrificed, while the remaining six rats continued to receive treatment as before. On the 8th day, all the rats were sacrificed. Specimens were fixed, and histology slides were made. Further, microscopic slides were observed and scored.Result: Both the 7.5% and 15% standardized ethanol extracts of roselle calyx were found to reduce the ulcer diameter and inflammation score. No swelling or redness was observed.Conclusions: The application of 7.5% standardized ethanol extract of roselle calyx for 7 days is equally as effective as the application of 0.1% triamcinolone acetonides, except in terms of the decrease in the inflammation score.
