Ethanol Extracts

Ethanol extracts of different traditional Malaysian plants (Polygonum minus, Andrographis paniculata, Curcuma xanthorrhiza,Momordica charantia and Strobilanthes crispus) were evaluated for their gastroprotective activities. In this experiment several groups of Sprague Dawley rats weighing 200–250gm were used. The first group was pre treated with (0.25% w/v) carboxymethyl cellulose (negative control, 5 ml/kg), the second group was pre treated with 20 mg/kg omeprazole (positive control) and the other groups were pretreated with the selected Malaysian medicinal plants in two different doses 250 and 500 mg/kg respectively. After 60 min all the rats were treated with 95% ethanol for ulcer induction. Rats were sacrificed 1 h after induction and the stomachs were analyzed for gross and histological changes. Negative control group showed extensive lesions of gastric mucosal layer, whereas rats pretreated with omeprazole and Malaysian plants showed significant and dose dependent reduction in gastric lesions. Amongst, the selected plants Polygonum minuspotentially promote better inhibition percentage of ulcer area. So that we can conclude that Polygonum minus could be the selective plant as an antiulcerogenic agent for the treatment of gastric ulcer.

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.

 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.

Objective: To observe the difference of testosterone levels in adult male Sprague Dawley rats treated with combination of cisplatin and vitamin E compared to those treated with cisplatin only. Material & Methods: We used 24 adult male Sprague Dawley rats weight 200–300 grams and randomly assigned into 4 groups (n=6). Rats in negative control group (NC) were given intraperitoneal normal saline injection, while the positive control (PC) group were injected with cisplatin 5 mg/kgBW at the end of the 3rd week. Two other groups, P1 and P2, were injected with cisplatin 5 mg/kgBW and given vitamin E orally 50 mg/kgBW and 200 mg/kgBW, respectively. Cardiac blood was aspirated at the end of the 7th week and processed for analysis of testosterone levels. Results: We recorded a significantly lower testosterone levels in rats treated only with cisplatin 5 mg/kgBW (CP) compared to those in CN group (p=0.006), and those receiving combination of cisplatin and vitamin E 50 mg/kgBW (p=0.003) and 200 mg/kgBW (p=0.001). Though not significant, testosterone levels were higher in P2 group than in P1 group (p=0.702). Conclusion: Exposure to cisplatin can lower testosterone levels in white rats, and the administration of vitamin E gives protection against such effect.

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 Aims This study investigated the effects of buprenorphine treatment on pain and welfare parameters and model specific parameters in a rat model of monoarthritis to eliminate unnecessary pain from this model. Methods 32 male Sprague Dawley rats were divided into four groups: (1) A negative control without arthritis receiving no analgesia. (2) A positive monoarthritic control group receiving no analgesia, but subcutaneous saline injections twice a day. (3) A positive control with monoarthritis receiving subcutaneous carprofen once a day and saline once a day. (4) A group with monoarthritis receiving subcutaneous buprenorphine twice a day. Monoarthritis was induced with an injection of 0.02 ml Complete Freund’s Adjuvant intra-articularly in the left tibiotarsal joint. Treatment with analgesia was initiated at day 15 and the rats were euthanized at day 23. Results The induced monoarthritis elicited a pronounced acute inflammation. Several parameters such as bodyweight, mobility, stance, joint-stiffness and lameness scores were affected. A marked mechanical hyperalgesia in the tarsal area was observed by Electronic Von Frey testing, but no severe compromise of the animal welfare was seen at any time. Signs of chronic development began to appear from day 10 after the monoarthritic induction. No significant change in serum cytokines and faecal corticosterone measurements was found after administration of buprenorphine. A minor decrease in body weight was seen, and a higher pain tolerance to mechanical stimuli was observed, indicating pain alleviation. The histological examination confirmed monoarthritic development in all monoarthritic rats and revealed periarticular lesions suggesting diffusion of adjuvant from intra-articular injection site to the periphery. Conclusions The study demonstrated that buprenorphine has an analgesic effect in the adjuvant induced monoarthritic rat model, without obvious interference with the development of arthritis.

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.

The purpose of this study was to evaluate the osteogenesis of tetracycline blended chitosan membranes on the calvarial critical size defect in Sprague Dawley. An 8 mm surgical defect was created with a trephine bur in the area of the midsagittal suture. Forty rats were divided into four groups: negative control group, positive control group and two experimental groups. Three types of membranes were made and a comparative study was done. One type of non-woven membrane was made by chitosan for positive control. The other two types of non-woven membranes were made by immersing non-woven chitosan into either the tetracycline solution or the chitosan-tetracycline solution. Histologic analysis was done at 2 weeks and 8 weeks of healing periods. We concluded that that the use of tetracycline blended chitosan membrane on the calvarial defects in rats has a significant effect on the regeneration of bone tissue in itself. In addition it implicates that tetracycline blended chitosan membrane may be useful for guided tissue regeneration.
