D-amphetamine-induced depletion of energy and dopamine in the rat striatum is attenuated by nicotinamide pretreatment

The present study examined the effects of nicotinamide on the D-amphetamine (AMPH)-induced dopamine (DA) depletion and energy metabolism change in the rat striatum. In chronic studies, co-administration of AMPH with desipramine, a drug that retards the metabolism of AMPH, (10 mg/kg, intraperitoneal [i.p.], respectively) caused a significant decrease of striatal DA content measured 7 days later. Pretreatment with nicotinamide (500 mg/kg, i.p.), the precursor molecule for the electron carrier molecule nicotinamide adenine dinucleotide (NAD), attenuated this effect of AMPH, whereas itself exerted no long-term effect on striatal DA content. In acute studies, a decrease in striatal adenosine triphospate/adenosine diphosphate (ATP/ADP) ratio was found 3 h after co-injection of AMPH and desipramine. However, nicotinamide pretreatment blocked the reduced striatal ATP/ADP ratio and resulted in a striking increase in striatal NAD content in AMPH-treated rats. Furthermore, nicotinamide was noted to increase striatal ATP/ADP ratio and NAD content in saline-treated rats. These findings suggest that nicotinamide protects against AMPH-induced DAergic neurotoxicity in the striatum of rats via energy supplement.     

狼疮性肾炎病人血浆内皮素级意义

①目的 探讨狼疮性肾炎（ＬＮ）病人血浆内皮素级意义。②方法 采用放射免疫分析法,对２０例正常人和２７例ＬＮ病人的血浆内皮素（ＥＴ－１）含量进行了测定。③结果 ＬＮ病人血浆ＥＴ－１水平高于正常人,而伴有肾功能损害和高血压的ＬＮ病人血浆ＥＴ－１水平高于ＬＮ组和正常人（Ｆ＝５．２８,ｑ＝７．５６￣１１．１０,Ｐ〈０．０５）。ＬＮ病人血浆ＥＴ－１水平与血尿素氮、肌酐呈正相关（ｒ＝０．４１２,０．５０８,Ｐ     

两种LASIK微型角膜刀的临床应用探讨

目的　比较ＫＮ－ ５０００ 型微型角膜刀与Ｍｏｒｉａ 微型角膜刀在ＬＡＳＩＫ 术中制作角膜瓣时的优缺点。方法　选用连续病例５６ 例１０３ 眼,随机分ＫＮ 组和Ｍｏｒｉａ 组,ＫＮ 组２８ 例５３眼,术前近视度数平均为－ ９－２１±７－４１Ｄ,散光≤－５－００Ｄ,Ｍｏｒｉａ 组２８ 人５０ 眼,术前近视度数平均为－１０－４７±３－７３Ｄ,散光≤－２－５０Ｄ,术中分别用ＫＮ－５０００ 微型角膜刀和Ｍｏｒｉａ 微型角膜刀制作角膜瓣。结果　两组病例角膜瓣边缘整齐。基质面：ＫＮ组全部术眼光滑、规则,Ｍｏｒｉａ 组部分术眼有“搓衣板”现象。瓣异常：ＫＮ组游离瓣２ 眼,Ｍｏｒｉａ 组不全瓣５ 眼。ＫＮ组角膜瓣质量优于Ｍｏｒｉａ 组,瓣异常率低于Ｍｏｒｉａ 组。结论　ＫＮ－ ５０００ 微型角膜刀在ＬＡＳＩＫ术中制瓣时性能及安全性、稳定性优于Ｍｏｒｉａ 组微型角膜刀。ＫＮ－ ５０００ 微型角膜刀还具有良好的易学性和进行ＬＡＳＩＫ角膜板层移植的功能。     

Concordant childhood acute lymphoblastic leukemia in monozygotic twins

Two 4-year-old monozygotic Chinese, female twins developed concordant childhood acute lymphoblastic leukemia (ALL) within an interval of about 2 weeks. Based on morphology and cytochemistry findings of the bone marrow blast cells, a diagnosis of ALL, L1 was made. Immunophenotyping showed the blast cells of both twins expressed similar antigens, i.e. HLA-DR, CD10, CD13, CD19, CD22 and CD34. Identical blood group, same HLA (human leucocyte antigen) genotype, sex and similar appearance suggest that the twins are monozygotic. Since the bone marrow leukemic cells of both twins were identical in morphology and expressed the same antigens with almost similar percentages of positivity, it is likely that the blast cells were derived from the same single clone. Based on the single clone hypothesis, the leukemogenic event must have arisen in utero in one twin and the cells from the abnormal clone then spread to the other twin via shared placental anastomoses.     

Anthropometric measurements and body composition of selected national athletes

This study was conducted to determine the anthropometric measurements and body composition of selected national athletes. A total of 84 male athletes from 10 different types of sports and 24 female athletes from 5 types of sports were studied. The height and body weight of subjects were measured using the SEGA weighing balance with height attachment. Skinfold thickness measurements were taken using the Harpenden Calipers at 4 sites (biceps, triceps, subscapular and suprailiac). Percentage of body fat was calculated from the sum of 4 measurements of skinfold thickness. Based on body mass index (BMI), most of the male (68 subjects or 81%) and female (19 subjects or 79%) athletes were classified as normal. The percentage average body fat for both male and female athletes were 13.8 ± 4.5% and 24.7 ± 5.3%, respectively. The male and female athletes also had lower percentage of body fat when compared to non-athletes, however these athletes had slightly higher percentage of body fat when compared to those in selected countries.
