EATING AND HYPOTHALAMIC STIMULATION

Food intake in the rat is increased during electrical stimulation of the hypothalamus only when food is present during the period of stimulation. Increased intake can be maintained for as long as 39 days, providing the stimulation is repeated each day.     

OBESITY AND PLASMA LEVELS OF INSULIN AND GROWTH HORMONE

Studies of serum levels of glucose, free fatty acids, insulin, and growth hormone during prolonged fasting suggest that insulin and growth hormone are not responsible for certain metabolic abnormalities accompanying obesity.     

ENVIRONMENTAL STRESS AND CHOLESTEROL ESTERIFICATION IN PLASMA AND LIVER

The stress created in rats by placing them in a restraining cage significantly altered the metabolism of liver cholesterol esters. Thus, the stresses created by handling animals during an experiment may significantly alter experimental results.     

父母职业与儿童白血病

儿童白血病病例-对照研究,发现母亲孕期从事化学品生产及处理,金属冶炼及处理、农业及林业生产、制药及医务等工作与子代白血病危险度增高有关,母亲孕期接触苯、汽油、农药等,其子代急性淋巴及非淋巴细胞白血病均见升高,但苯的暴露与急性非淋巴细胞白血病关系更为密切。未发现父亲职业及职业暴露与儿童白血病有关。     

DEHYDROEPIANDROSTERONE AND OBESITY

A recent study suggests that the reduced urinary excretion of dehydroepinadrosterone and the elevated red blood cell glucose-6-phosphate dehydrogenase activity seen in obese subjects may be reversed during periods of weight loss.     

INFLUENZA AND PNEUMONIA

This symposium summarizes the opinions of several widely known health workers on the modes of infection, spread, prevalence and nature, epidemiology, and legislative and executive management of influenza and pneumonia-the two diseases which so greatly increased our morbidity rates during the winter season.     

POLIC ACID AND PREGNANCY

The requirements for folic acid during pergnancy, and the possible risks of de-ficiency to the mother and child are discussed.     

INFLUENZA AND PNEUMONIA

This symposium summarizes the opinions of several widely known health workers on the modes of infection, spread, prevalence and nature, epidemiology, and legislative and executive management of influenza and pneumonia—the two diseases which so greatly increased our morbidity rates during the winter season.     

ZINC AND PARTURITION

A low zinc intake during gestation in the rat causes a severe disturbance in her ability to deliver her young and to display normal maternal behavior. Recent studies identified some of the physiological alterations which accompany this phenomenon.     

STARVATION AND LACTIC DEHYDROGENASE

Parallel decreases in hepatic lactic dehydrogenase activity and nitrogen content occur during six days of starvation in the rat.     

胆囊管变异与胆囊切除术

胆囊切除术是腹部外科的常见手术之一,胆囊管的处理是胆囊切除术的关键步骤,胆囊管的变异可造成手术的困难,也是胆道医源性损伤的一个主要原因。方法：回顾性分析我院２０年来在胆囊切除术中发现的１２５例胆囊管变异,对其病理分型及术中的处理方法作一探讨。结果：术中胆总管损伤８例,胆囊管处理不当致术后形成胆汁性腹膜炎４例,全组无死亡。结论：胆囊管的变异是造成胆囊切除术中胆道医源性损伤的主要原因,术中应根据胆囊管的变异情况作不同的处理。     

INFLUENZA AND PNEUMONIA

At the Chicago meeting this author spoke in the General Sessions and was asked to continue beyond the time limit. There was discussion and endorsement. It was characterized to be a treatment of the older fashion much employed by physicians during the epidemic.

EXERCISE AND CHOLESTEROL CATABOLISM

Excretion of "CO. after 26."C-choleslerol administration was greatly increased during exercise as compared with a rest period.     

母乳与新生儿粪便中乳铁蛋白含量测定及相互关系的探讨

本文用火箭电泳法和酶联免疫吸附法分别测定了人奶和不同喂养方式新生儿粪便乳铁蛋白(LF)。结果显示,正常产妇1～8天初乳LF含量为6.88±3.10mg/ml,1～4个月成熟乳为3.18±0.87mg/ml。产后头3天初乳LF含量最高,之后渐下降,成熟乳阶段趋于稳定。不同喂养方式新生儿粪便LF含量有非常显著性差异(P<0.01)。粪便LF检出率,母乳喂养儿为100％,人工喂养儿仅60％。胎便中可检出小量,检出率为35％。母乳与新生儿粪便LF同步测定结果显示,母乳中高浓度LF对母乳喂养儿肠道LF含量有肯定的影响。人体肠道内源性LF的产生,从胎儿期就已开始,但在新生儿早期产生十分有限。母乳喂养能通过向新生儿传递包括LF在内的多种免疫物质,弥补生命早期自体产生的不足。     

EXERCISE AND GASTROINTESTINAL ABSORPTION IN HUMAN BEINGS

Intestinal absorption of moderate quantities of carbohydrate, salt, and water taken during exercise did not differ from absorption during rest periods.     

去氧肾上腺素、麻黄素对腰硬联合麻醉下剖宫产母婴的影响

目的探讨和麻黄素相比,去氧肾上腺素用于腰硬联合麻醉下剖宫产,对母体和新生儿的影响。方法选择择期剖宫产术病人60例,ASAⅠ～Ⅱ级,随机分为两组。分别给予静脉泵注去氧肾上腺素100μg/ml(P组)和麻黄素3mg/ml(E组)维持术中收缩压在基础水平。记录术中HR、BP、SpO2、ECG,采集新生儿脐静脉、脐动脉血监测pH、PO2、PCO2,记录产妇术中恶心、呕吐发生率。结果E组术中HR、RPP高于P组(p<0.05);P组新生儿脐静脉血pH、PO2高于E组(p<0.05);P组术中恶心、呕吐发生率低于E组(p<0.05)。结论和麻黄素相比,去氧肾上腺素用于维持腰硬联合麻醉下剖宫产患者的术中血压,能降低新生儿酸中毒的发生率和降低产妇术中恶心、呕吐的发生率。     

PLASMA FREE FATTY ACIDS AND COLD EXPOSURE

Fasting human subjects exhibit greater increases in plasma free fatty acids during acute cold exposure than during rest in a comfortable environment, but do not develop significant ketosis.     

DIET AND WORK METABOLISM

The respiratory quotient during exercise is influenced by the carbohydrate content of the previous diet. The results suggest that under certain conditions fat may be the major fuel of the working muscle.     

ETHANOL AND ANGINA PECTORIS

Ethanol actually decreases, rather than increases, the time in which angina pectoris appears in exercising patients with severe coronary artery disease. ST-segment depression is increased during exercise suggesting failure on the part of the subject to recognize angina pains.
