The results of the preoperative Co 60 irradiation and BVMM (bleomycin, vincristine, mitolactol, methotrexate) chemotherapy were compared. Both treatments were used in 50-50 advanced squamous cell cancer of the oral cavity. The general condition, size of lesion and age of the patients were similar. Surgery in the irradiated group was significantly more radical at the primary sites. Local recurrences during a three-year follow-up period were diagnosed in 36% from the radiotherapy group, whilst 8% such recurrences diagnosed in the chemotherapy group. There was no significant difference in the radicality of lymph node surgery. Lymph node recurrences occurred in 8% from the irradiated group, whilst 22% was diagnosed in the chemotherapy group. The main opinion is that BVMM chemotherapy and irradiation can be used to support one another in the interest of better result, like preoperative chemo- and postoperative radiotherapy. 相似文献

Nauclea latifolia Smith (Rubiaceae) is used in traditional medicine in Togo to treat illnesses such as malaria, fever and stomach-ache. The present investigation was undertaken to evaluate the effect of leaf and root extracts on hyperthermia and paw oedema. The extract from the leaves and roots, at different doses, significantly reduced the hyperthermia and paw oedema. These results partially confirm the use of Nauclea latifolia in traditional medicine. 相似文献

The root of Bridelia ferruginea is traditionally used as a treatment for type 2 diabetes. The present study was investigated to evaluate the effect of Bridelia ferruginea root bark fractions on some markers of type 2 diabetes on fructose drinking mice.Materials and methods
Mice received a solution of fructose 15% during 42 days ad libitum; at the 15th day to the 42nd day, they received distilled water for fructose drinking control group, metformin 50 mg/kg per day or fractions 50 mg/kg per day for treatment groups. The normal control group received only distilled water during the experiment. After 6 weeks of experiment, OGTT, fasting blood glucose, plasma insulin, triglycerides (TG), total cholesterol, AST and ALT levels were measured.Results
Fructose drinking control group (F) showed significant (p<0.001) increase of glucose tolerance, plasma levels of total cholesterol, triglycerides and insulin index for insulin resistance (Homeostasis Model Assessment ratio HOMA-IR) as compared to normal control mice. In treated groups, there was a significant reduction of glucose intolerance respectively 74% (p<0.001), 25% (p<0.5) and 92% (p<0.001) for ethyl acetate fraction, acetone fraction and metformin at the same dose of 50 mg/kg per day during 4 weeks administration. In ethyl acetate fraction and metformin treated groups, biochemical parameters and insulin index were significantly (p<0.001) lower than that of fructose drinking control group.Conclusions
This indicates that Bridelia ferruginea root bark ethyl acetate fraction improved insulin resistance as metformin significantly in type 2 diabetes. 相似文献6.

Campylobacter are zoonotic bacteria and a leading cause of human gastroenteritis worldwide with Campylobacter jejuni and C. coli being the most commonly detected species. The aim of this study was to detect Campylobacter in humans and livestock (chickens, ducks, pigs, cattle, water buffalo, quail, pigeons and geese) in rural households by routine culturing and multiplex PCR in faecal samples frozen before analysis. Of 681 human samples, 82 (12%) tested positive by PCR (C. jejuni in 66 samples and C. coli in 16), but none by routine culture. Children were more commonly Campylobacter positive (19%) than adult males (8%) and females (7%). Of 853 livestock samples, 106 (12%) tested positive by routine culture and 352 (41%) by PCR. Campylobacter jejuni was more frequent in chickens and ducks and C. coli in pigs. In conclusion, Campylobacter proved to be highly prevalent by PCR in children (19%), ducks (24%), chickens (56%) and pigs (72%). Routine culturing was insufficiently sensitive in detecting Campylobacter in field samples frozen before analysis. These findings suggest that PCR should be the preferred diagnostic method for detection of Campylobacter in humans and livestock where timely culture is not feasible. 相似文献

In African traditional medicine, Ageratum conyzoides has been used as purgative, febrifuge, anti-ulcer and wound dressing. To date there is no safety information about long term use of Ageratum conyzoides which contains pyrrolizidine alkaloids, a class of hepatotoxic and carcinogenic phytochemicals. This study aims to evaluate the 90 days subchronic toxicity and in vitro toxicity of Ageratum conyzoides.Materials and methods
Three groups of 8 rats (4 males and 4 females) received distilled water (control), 500 and 1000 mg/kg of the extract daily for 90 consecutive days by oral gavage. The animals were observed daily for abnormal clinical signs and death. Body weight, relative organ weight, haematological and biochemical parameters of blood as well as heart, kidney, liver and spleen tissues histology were evaluated.Results
After 90 days administration, Ageratum conyzoides increased significantly (p<0.05) the relative weight of the liver, the spleen and kidney as compared to control group. Ageratum conyzoides increased also significantly (p<0.05) ALP, ALT, AST and blood glucose. Furthermore, an increase in the number of platelets associated with a normocytic and normochromic anaemia was observed. The cytotoxicity, determined by the MTT test and neutral red assay, has shown that the cytotoxicity of hydroalcoholic extract of Ageratum conyzoides and its total alkaloids was very close.Conclusions
Our results have shown that Ageratum conyzoides at 500 and 1000 mg/kg can induce liver, kidney and haematological disorders. These toxics effects can be attributed to its total alkaloids especially to pyrrolizidine alkaloids which are present in this plant. 相似文献9.
Ethanolic extract of Pluchea ovalis roots inhibit acetylcholine-induced bronchoconstriction observed in asthma. To understand the mechanism of P. ovalis root extract on airway smooth muscle contraction, we investigated the anti-cholinergic effect of the ethanolic extract on isolated isolated tracheae of the Wistar rat. For this purpose, three experimental conditions of incubation were used: idomethacin, indomethacin+propranolol or indomethacin+propranolo+ promethazine. The extract was applied in all three conditions at 0.25 mg/ml for 10 minutes prior to cumulative doses of acetylcholine (10(-8) to 5.10(-4) g/ml). The extract reduced acetylcholine-induced contraction and could have an antagonistic effect on muscarinic receptors of the rat trachea. 相似文献
