Secretory immunoglobulin A (sIgA) is the dominant immW1oglobulin in human milk, and apart from the obvious contribution it makes towards the protection of the infant, sIgA may also form an important part of the defense of the mammary gland. This report involves a mother (M8) who participated in a research study investigating the relationships between symptoms and changes in the physiology of th...

Transmission of Trichinella to humans is still a global public health concern. Although theoretically possible, vertical transmission of Trichinella has rarely been investigated. In June 2005 an outbreak of trichinellosis was reported in Udomxay province, the Northern Lao Peoples' Democratic Republic (PDR). In February and March 2006 we performed a study of all pregnant and lactating mothers an...

PURPOSE Urinary tract infection (UTI) is an ascending infection of fecal uropathogens, urogenital lactobacilli are suggested to play a role in the prevention of UTI. This study was to investigate whether lactobacillus mixture (LM) could prevent the experimental infantile UTI. MATERIALS AND METHODS The LM were composed of three lactobacillus strains (L. gasseri, L. rhamnosus, and L. reuteri). ...

Previous studies at 21 °C and 5 °C suggest that in Swiss mice sustained energy intake (SusEI) and reproductive performance are constrained by the mammary capacity to produce milk. We aimed to establish if this constraint also applied at higher ambient temperature (30 °C). Female Swiss mice lactating at 30 °C had lower asymptotic food intake and weaned lighter litters than those at 21 °C. Restin...

Maternal behavior in mammals is the result of a complex interaction between the lactating dam and her developing offspring. Slight perturbations of any of the components of the mother-infant interaction may result in alterations of the behavior of the mother and/or of the offspring. We studied the effects of exposure of female CD-1 mice to the estrogenic chemical bisphenol A (BPA) during fetal ...

1. Female rats were undernourished from birth through replacement for 12 h/d of the lactating mother by a nipple-ligated mother. This resulted in slow growth so that 22 d of age the body-weights equalled those of well-nourished animals at 14 d. 2. At 14, 17, 20 and 22 d groups of eight to ten animals each of undernourished and well-nourished rats were autopsied, serum follicle-stimulating hormo...

Using lactation in mice as a model, we sought to determine whether ceilings on sustained energy expenditure reside in the capacities of energy-acquiring and input organs (such as the intestine) or of energy-expending and output organs (such as the mammary glands). To distinguish between these possibilities experimentally, we surgically varied the teat number of lactating mother mice while simul...

Lactating adenomas are rare benign tumors of breast, frequently associated with pregn lactation. They are common in the third trimester of pregnancy during second and third decade. They present similarly as other benign lesions of breast and differentiation from them preoperatively is difficult both clinically and radiologically. I epithelium leading to formation of a we remains the definitive ...

Lactating female rats without their pups exhibit lower HPA responsiveness to stress than nonlactating females. However, responsiveness to stress is similar when lactating females are tested with their pups and the stressor involves a potential threat to the offspring. This study constitutes the first comparison of stress responsiveness in lactating and nonlactating female nonhuman primates. Sub...

Supportive breastfeeding policies in the hospital constitute the foundation for initiation of successful breastfeeding by mothers, constant reinforcement and support to all lactating mothers is however essential to maintain lactation. The objective, methodology and outcome of the Lactation Management Clinic which constitutes a hospital-based mother support group is described. The study was carr...
