Histamine: a role in normal drinking

Little is known about the physiological mechanisms that control normal drinking and, in particular, drinking around mealtime. This problem has recently been penetrated by experiments evaluating a role for histamine in drinking elicited by eating. This work supports the hypothesis of a preabsorptive, pregastric, vagally-mediated, histaminergic component of drinking elicited by eating in the rat.     

Weanling diarrhoea in The Gambia: implications of a jejunal intubation study

Abnormalities in jejunal flora and bile salt metabolism were most marked in the youngest members of a group of Gambian village children in the weanling age group. These may be linked with the profound change in diarrhoeal morbidity, particularly diarrhoea-induced growth impairment, which occurs as soon as breast-fed infants are regularly supplemented. The pathogenesis of these changes is not understood. The presence of small bowel colonization did not appear to be a causal factor but, it is speculated, its appearance may mark the development of a post-enteritis enteropathy which is responsible for the weanling diarrhoea syndrome and which is caused and perpetuated by traditional weaning foods.     

饮用水源中麦氏弧菌的分布与腹泻病关系的研究

自腹泻病人和饮用水源等不同检材中分离到麦契尼可夫孤菌２９２株．其中产色素麦契尼可夫弧菌２５株；该菌在饮用水源中分离的最适水温为６～１０℃，０～５℃次之，随着水温的上升其阳性检出率呈现明显的下降趋势．根据该菌的生化学分型模式，２９２株麦契尼可夫弧菌全部可以分型．分型结果显示人源株和水源株生物型完全吻合，均是Ⅰ型居首位，Ⅷ型次之，表明由该菌引起的腹泻与水源污染有密切关系．
