Objective : To study the effect of early intervention and rehabilitation in the expression of aquaporin-4 and ultrastructure changes on cerebral palsy pups model induced by intrauterine infection. Methods : 20 pregnant Wistar rats were consecutively injected with lipopolysaccharide intraperitoneally. 60 Pups born from lipopolysaccharide group were randomly divided into intervention group (n=30) and non-intervention group (n=30); intervention group further divided into early intervention and rehabilitation group (n=10), acupuncture group (n=10) and consolidate group (n=10). Another 5 pregnant rats were injected with normal saline intraperitoneally; 30 pups born from the normal saline group were taken as control group. The intervention group received early intervention, rehabilitation and acupuncture treatment. The motor functions of all pups were assessed via suspension test and modified BBB locomotor score. Aquaporin-4 expression in brain tissue was studied through immunohistochemical and western-blot analysis. Ultrastructure changes in damaged brain and control group were studied electron-microscopically. Results : The scores of suspension test and modified BBB locomotor test were significantly higher in the control group than the intervention and non intervention group (p<0.01); higher in the intervention group than the non-intervention group (p<0.01). The expression of Aquaporin-4 was lower in intervention and non intervention group than in the control group (p<0.01); also lower in non-intervention group than the intervention group (p<0.01). Marked changes were observed in ultrastructure of cortex and hippocampus CAI in brain damaged group. Conclusion : Early intervention and rehabilitation training can improve the motor function in offspring with brain injury and reduce the expression of aquaporin-4 in damaged brain.

The developmental features, growth and organogenesis of Macroorchis spinuiosus were observed in albino rats. Globular and thick walled metacercariae, possessed a stylet, Y-shaped excretory bladder and extracecal testes. Un albino rats, M. spinulosus showed habitat shifting. The majority of M. spinulosus reside in the jejunum for the first four days post Infection (p.i.) and migrate to the duodenum at the later stage of infection. M. spinulosus grew rapidly during the first four days and reached full maturity at 14 days p.i. and later reduced in size. The ovary was separated from the genital primodium at one day p.i. The seminal vesicle appeared on the third day and divided into two sacs on the fourth day p.i. and intrauterine eggs and sperm mass were produced on the fourth day. Organogenesis and enlargement of reproductive organs governed the growth of M. spinulosus. The similarity of related species of the genus Macroorchis to M. spinulosus was discussed In consideration to developmental features.

Pelvic actinomycosis is an uncommon infectious disease. It induces a chronic, suppurative illness characterized by an infiltrative and granulomatous response and, thus, the clinical and radiologic findings may mimic other inflammatory and neoplastic conditions. A 56-year-old female with a long-standing intrauterine device was diagnosed with pelvic actinomycosis manifesting as a large uterine mass with locally infiltrative spread into surrounding tissue that mimicked uterine malignancy. Actinomyces israelii infection was confirmed with a surgical specimen, and the patient was treated with antibiotic medication. Pelvic actinomycosis must be included in the differential diagnoses of patients with an infiltrative pelvic mass extending across tissue planes or in patients with findings of multiple microabscesses, particularly in a patient with an intrauterine device, even the lesion primarily involves the uterus.

성인에서 A형 간염은 현증 감염이 대부분이지만, 소아에서는 무증상 또는 경한 증상을 보이는 경우가 많았다. 그동안 외국에서는 임신 및 분만 기간 동안에 발생한 A형 간염의 산모와 이로 인한 신생아 A형 간염에 대한 증례 보고가 드물지 않게 있었다. 국내에서는 20대와 30대의 젊은 성인에서 A형 간염에 대한 항체 양성률이 낮아지고 있는 가운데, 이들 산모들의 A형 간염에 대한 위험성이 증가하고 있는 상황이며, 아직까지 국내에서는 A형 간염에 이환된 신생아에 대한 증례 보고가 없었다. 이에 저자들은 A형 간염 산모로부터 이환된 것으로 보이는 급성 A형 간염 신생아를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

거대세포바이러스 감염은 선천감염의 가장 흔한 원인 중의 하나이다. 본 증례는 쌍생아에서 다른 임상 양상을 보인 선천 거대세포바이러스 감염 증례에 대한 국내 첫 보고이다. 31세 초산부가 쌍생아(2 융모막, 2 양막)를 임신하였다. 임신 34주 산전 초음파에서 한쪽 태아의 크기가 작고 양측 뇌실 확장증이 발견되었으며 임신 37주경에 제왕절개로 분만하였다. 첫 번째 신생아는 남자로 출생 체중 2,410 g, 아프가 점수 8/9점으로 출생하였으며 두 번째 신생아는 여자로 출생 체중 1,380 g, 아프가점수 5/8점으로 출생하였다. 두 번째 신생아는 자궁 내 성장지연, 소두증, 소하악증, 사지 관절의 강직을 보였다. 불일치 쌍생아에 대한 원인을 찾기 위한 검사를 진행하였으며 두 번째 신생아의 혈액검사에서 거대세포바이러스 immunoglobulin M이 양성반응을 보였으며 소변과, 혈액, 뇌척수액에서 거대세포바이러스 중합효소연쇄반응이 양성소견을 보였다. 반면에 정상으로 출생한 남아의 거대세포바이러스에 대한 검사는 모두 음성이었다. 감염된 환자의 안과적 검진에서 거대세포바이러스 망막염이 관찰되었고, 후에 실시한 청력검사에서 양측의 감음 난청이 확인되었다. 환자는 ganciclovir 치료를 받았으며 현재 여아는 심한 발달지연이 있으며 침대에서 누워서 생활하는 중이다. 이와 같이 쌍생아에서의 선천 거대세포 바이러스 감염증이 한 명에게만 발생하는 경우의 원인은 현재까지 명확하지 않다. 하지만 이 증례를 통하여 심한 불일치 쌍생아의 경우에 선천 거대세포바이러스 감염의 가능성을 고려해 보아야 한다.

In the course of Clonorchis sinensis infection, antigens presented to the hosts may be in a close relation to growth of the fluke. The antigenic proteins stimulating IgG antibody production were chronologically identified by immunoblot and localized by immunogistochemical staining. In the early stage of infection until 12 weeks post-infection (PI) , antigens were proteins with molecular mass larger than 34 kDa which were derived from the tegument, testes and intrauterine eggs. After 20 weeks PI antigens recognized were 29, 27 and 26 kDa proteins from the intestine, excretory bladder and reproductive organs. It is suggested that the tegumental proteins are the most potent antigens and the excretory-secretory proteins with middle molecular mass of 26-45 kDa contribute to the high level production of antibodies after 20 weeks of the C. sinensis infection.

Primary cytomegalovirus (CMV) infection during pregnancy can cause congenital defects. Available data for CMV infection during pregnancy in north China are inadequate. The aim of this study was to evaluate the epidemiology of maternal CMV infection and explore the incidence of congenital infection. In this prospective study, serum CMV IgG and IgM antibodies were measured in 2,887 pregnant women using ELISA, and the IgG avidity test was performed on all IgM-positive subjects. The seroprevalence of anti-CMV IgG was 94.70%, and of anti-CMV IgM was 1.28%. CMV IgG prevalence increased significantly with age (p < 0.01). Women living in downtown areas showed higher IgG prevalence than those residing in urban areas (p = 0.023). CMV-IgM seroprevalence was highest in autumn (p = 0.021). There was no difference in IgM seroprevalence by age, socioeconomic status, geographical area, or gravida. The rate of primary CMV infection was 0.45% (13/2,887) at the first trimester. The seroconversion rate during pregnancy was 0.76% (22/2,887). One woman underwent seroconversion during pregnancy and gave birth to an infant with asymptomatic CMV infection. Congenital CMV infection was diagnosed in five of the 14 infants from 14 mothers with active infection, for a vertical transmission rate of 35.71% (5/14). Three infants were asymptomatic, whereas two infants presented symptomatic infection with hearing deficits. Although CMV IgG prevalence is relatively high in north China, significant attention to primary CMV infection during pregnancy is still needed.

An attempt to reproduce pyometra by means of experimental uterine infection was conducted with the 10 mongrel hitches of the anestrus, proestrus, metestrus, and postpartum uterine involution stages. Organism used was hemoltic E. coli. origially isolated from uterine pus of a bitch that had the canine pyometra. One ml of broth culture containing $2{\times}10^6$ CFU was inoculated into the uterine horn with the uterine cervix ligated. Aか bitches were ovariohysterectomized at the 7th or 14th day after inoculation and the uterus was provided for macroscopic and microscopic observations. An experimental production of pyometra was successful in 7(70%) of 10 mongrel bitches, and the incidence of pyometra was seen 100% in the stage of anestrus, 100% in the stage of metestrus, 50.0% in the stage of pyomestrus, and 33.359 in the stage of uterine involution. Histologically, these uteri were characterized by the presence of cystic. endomeetrial hyperplasia(CEH) and acute endometritis superimposed on the cystic hyperplasia. And the pyometra with CEH could be seen 66.7% in metestrus 50% in anestrus, 33.3% in involution and in 0% in proestrus stage. Blood progesterone concentrations were showed as a normal range of the each stage of sexual cycle and any relationships between the progesterone concentrations and the incidence of pyometra were not observed.
