有关包皮过长分度及其手术适应证的雏议

目的探讨包皮过长程度的分度及其手术适应证。方法对636例高三男生包皮过长者,按其过长程度和20个月随访资料,区分成Ⅰ°、Ⅱ°、3组,即:Ⅰ°包皮过长不手术随访组285例;Ⅱ°包皮过长接受环切术和随访的199例,称为Ⅱ°过长手术随访组;Ⅱ°包皮过长未经手术担接受随访的98例,称为Ⅱ°过长不手术随访组。然后将3组进行比较、分析。结果Ⅱ°过长手术随访组发生疾病者仅3例(3/199,1.51%),Ⅱ°过长未手术随访组发生疾病者有39例(39/98,39.80%),2组间发病率有显著差异(P<0.01)。而Ⅱ°过长手术随访组和Ⅰ°过长未手术随访组(6/285,2.11%)之间无差异P>0.05。结论Ⅱ°包皮过长必须作环切(或环扎)手术治疗,而Ⅰ°包皮过长可以由患者自愿选择,但必须强调包皮保洁,否则亦难免罹病。提倡学龄(6岁)前施行包皮环切(环扎)术,有其深远好处,值得磋商。     

Odor of the muskox

The behavior of captive male muskoxen was observed closely during their characteristic superiority display, the anatomy of the preputial region was studied in two adults and three calves, and preputial washings and preorbital gland secretion were subjected to gas chromatography and mass spectroscopy. During the superiority display, the prepuce was everted to form a pendulous tube tipped with a fringe of matted hair. Owing to the movement of the animal, the urine that dribbled from the preputial opening was liberally applied to the long guard hairs of the belly. The superiority display was almost exclusively confined to dominant males and apparently accounted for their odor. In the quiescent state, the hair seen around the preputial opening was drawn inside and formed an 8 cm-wide band on the lining of the prepuce. The preputial washings contained large amounts of benzoic acid andp-cresol. The infraorbital gland secretion contained cholesterol, benzaldehyde, and a homologous series of saturated -lactones ranging from 8 to 12 carbons. The latter compounds and the natural secretion smell similar to the human nose.     

YAG激光切除包皮的探讨
