Environmental Conditions Responsible for Hibernation in Mammals

抄録 地球環境の温暖化によって,野生動物の繁殖や冬眠行動が大きな影響を受けることは容易に想像できる。しかし,実際に冬眠がどのような環境条件に影響されているのかは不明である。そこで,本研究では,冬眠行動を誘発する環境条件について検討を行った。冬眠する齧歯目として知られているシリアンハムスターをモデルとして用いた。冬眠の誘発にとって,気温の低下と日照時間の短縮は最も重要な要因であると考えられる。そこで,ハムスターを恒暗・低温環境下で飼育したところ,冬眠に入った。一方,これらの条件に加えて,飼料としてヒマワリの種子や高脂肪食を充分に与えたのち,給餌制限を行った場合,自由摂食をさせた個体と比較して,短期間で冬眠状態に入ることが見いだされた。このことは,食物の量と組成も冬眠行動の誘発に深く関連することを示唆するものである。また,これまでの実験結果から,体重の大きい個体ほど冬眠に入りやすいことがわかった。このことは,体内に蓄積された脂肪細胞から分泌されるレプチンなどのホルモンが,冬眠行動と関連する可能性を示唆するものである。これらの結果から,冬眠は,環境温度や日照時間,そして食物といった外部環境の変化と関連することが示唆された。 It is considered that global warming and exposure to endocrine disrupting chemicals can influence reproduction and hibernation of wildlife. However, environmental factors responsible for such behavioral differences are not well recognized. Therefore, in this study we analyzed environmental conditions that are critical for inducing hibernation. Non-seasonal hibernators, Syrian hamsters were used in this study. It has been pointed out that a low environmental temperature is an important factor to induce hibernation. So, hamsters were kept at a cold room. After about two or three months, they hibernated. Next, food restriction under the cold environment was performed. When the hamsters were fed sunflower seeds or high fat food not standard laboratory chow and then food supply was restricted, they efficiently hibernated in a shorter time period compared with those which were given free access to food. This suggests that the quantity and nutritional composition of food can affect hibernating behavior in addition to a low environmental temperature. We noticed that hibernation is more efficiently induced in obese hamsters than in thin ones. This may indicate that hormones derived from adipose tissue including leptin could be related to hibernation. These results suggest that hibernation might be associated with external environmental factors (environmental temperature and food composition). arabic 6 English 57

Effects of Anti-Tuberculous Drugs on Liver Function Profile in Libyan Patients with Tuberculosis

he present prospective study was designed to conduct a local survey on patients under anti-tuberculosis therapy hospitalized in Abo-Seta hospital, Tripoli, Libya from the safety point of view. The study was carried out on 75 inpatients. The effects of the used drugs on some hematological parameters and liver function biomarkers were monitored for six-month period of treatment. Our survey showed that tuberculosis affects people with low and medium levels of education and with no job. The frequency of adverse effects related to treatment with Abo-Seta hospital regimen were decreases in WBCs count (-38.7%), RBCs count (-32.1%), platelets count (-33%) and hemoglobin concentration (-35.5%). However, in most of the cases, it was not necessary to modify the treatment regimen because of such side effects. Some parameters showed spontaneous recovery as RBCs count (+22.1%) and hemoglobin level (+20.1%). Combined therapy of ethambutol, isoniazid, pyrazinamide, and rifampicin has been used in Abo-Seta hospital, as a regimen for tuberculosis infection, may be associated with a high risk of hepatic toxicity during first month of treatment. However, during the remaining five months there was a good recovery of liver enzymes profile. Upon the data obtained from the present study, it could be concluded that TB patient after 6 month of treatment didn't develop multi-drug resistant tuberculosis (MDR-TB arabic 13 English 83
