Globally, the poultry industry has a significant economic role, especially in Africa, where small farm holders contribute substantially to the national gross domestic product (GDP). Poultry feeding costs are rapidly increasing and account for over 60 percent of the production costs, but efficient feed formulation practices are a sustainable way of reducing the price. Ghanaian farmers use methods such as the rule of thumb, personal experience, and intuition to solve feed formulation problems. This study showed that the least-cost starter ration price decreased by 1.61%, and the least-cost finisher ration price decreased by 4.48%, indicating that non-conventional feed ingredients have a high economic value.

This study was undertaken to determine both the prevalence of the red cell irregular antibodies and the clinical significance of such antibodies in pregnant women. Among 1.047 patients who received complete prenatal care at the Severance Hospital, Yonsei Medical Center, 22(2.1%) were found to have irregular antibodies. The encountered irregular antibodies in order of frequency were : anti-D(7), anti-Le^a(5), anti-E(2), anti-Le^b(2), anti-E+c(1), anti-Le^a+b(1), anti-Jr^3(1), warm auto(1), cold(1), and unidentified(1). The antecedent maternal risk factors for development of irreaular antibodies such as previous abortion, Cesarean birth, or blood transfusion were observed in 17 patients(77.3%). Seven of the 22(31.8% 0 patients with irregular antibodies delevered infants with hemolytic disease. Only one of these seven required an exchange transfusion. Of the remaining 15 pregnancies with irregular antibodies, they showed normal perinatal outcomes. Our data suggests that irregular antibody screening in all prenatal patients is clinically useful for predicting the likelihood of hemolytic disease of the newborn.

The ovarian cancer is the second most common cancer of the female reproductive system. The epithelial ovarian cancer is the most common histopathologic type of malignant ovarian cancers. Despite the advances in the treatment of ovarian cancer made in rece t years, the 5-year survival rate continues to be low because many cases are still diagnosed at advanced stages. When ovarian cancers are detected and treated at early stage, the prognosis is more favorable. A retrospective study was performed in 35 cases of epithelial ovarian cancer at the Department of Obstetrics and Gynecology of Inje University Sangge Paik Hospital from Aug.1989 to Dec. 1995. We analysed age, clinical stage, histopathologic type, surgical procedure, and chemotherapy. The mean age was 49 years. The interval from onset of symptoms to diagnosis was 6 months or less in 74% of cases. The most common symptom was abdominal pain(40%). The largest diameter of epithelial ovarian cancer was 16-20 cm in 15 cases(43%). Of the 14 patients with stages I disease, 7 had stage II, 12 had stage III and 2 had stage IV. According to the histopathological classification of World Health Organization(WHO), serous cystadenocarcinoma was found in 14 cases, mucious cystadenocarcinoma in 13 cases, endometrioid carcinoma in 5 cases, malignant Brenner tumor in 1 case, clear cell carcinoma in 1 case, and undifferentiated carcinoma in 1 case. All patients underwent surgical staging and appropriate debulking surgery. 6 patient have died of ovarian malignancy and all of them are initially diagnosed as advanced ovarian cancer. From the above results, we concluded that early diagnosis and treatment were very important in the management of epithelial ovarian cancer.

Objective: Chromosomal abnormalities of abortuses have also been used to investigate the most common etiology of spontaneous abortion, but the frequency and the types of spontaneous abortions have also demonstrated considerable variation among in different countries and races. Methods: So as to studies of the frequency and type of chromosomal abnormalities of abortuses , a cytogenetic study of 74 abortuses and their aborters was performed from January, 1994 to December, 1997 in Hallym University Kangnam Sacred Heart Hospital. Results: The frequency of abnormal karyotypes in abortuses was 40.0%[28/70 cases], of autosomal trisomy 42.7% [12/28 cases], of monosomy X 21.4%[6/28 cases], of polyploidy 10.7%[3/28 cases] and of structural anomalies 25.0%[7/28 cases]. The earlier gestational age when the loss occurs, got the higher the likelihood to be chromosomally abnormal. Among trisomies, chromosomes 21[33%], 18[25%] and 16[17%] were prevalent. There was no statistical significance of the frequency of chromosomal abnormality according to maternal age, but trisomy was slightly increased at older age. Structural abnormalities were present in 7 cases; 2 cases were Robertsonian translocation and 5 cases were inversion. The origin of structural abnormalities were classified as De novo in 5 patients, and familial tendency in two. One of the parents of two translocation cases was carriers with abnormal karyotype. Two parents of translocation cases were carriers with abnormal karyotypes. Conclusion: Our findings support that cytogenetic study is worth-while in couples presenting with a history of spontaneous abortion or older age.

The p53 gene is a tumor suppressor gene and mutations in this gene play an import-ant role in the development of many human malignancies. The purpose of this study was to investigate the overexpression of p53 protein as a prognostic factor in invasive cervical cancer. Forty-three formalin fixed, paraffin wax embedded blocks of invasive cervical can-cers were examined using immunohistochemical staining with a monoclonal antibody against p53. The result were as follows: 1. Immunostaining for p53 consistent with overexpression was seen in 23.8%(5 of 21) of stage Ⅰ cancers and in 13.7%(4 of 22) of stage Ⅱ cancers. 2. Immunostaining for p53 consistent with overexpression was seen in 21.6%(8 of 37) of squamous cell carciomas and in 0%(0 of 6) of adenocarcinomas. 3. The incidence of p53 overexpression was 25.0%(1 of 4) in cases with lymph node metastasis, compared with 17.9%(7 of 39) in cases without lymph node metastasis. 4.. The incidence of p53 overexpression was 20.0%(8 of 40) in cases with less than 4 cm, compared with 0%(0 of 3) in cases with equal to or larger than 4cm. In conclusion, p53 overexpression was not associated with stage, histologic type, and tumor size. However, there were trend for p53 overexpression to increase in patients with lymph node metastasis.

Osteogenesis imperfecta is a relatively rare genetic condition of breakable bones with an incidence of 1 per 20,000~60,000. The clinical, genetic, and biochemical heterogeneity in osteogenesis imperfecta allows to least four subtypes to be distinguished. Prenatal diagnosis of osteogenesis imperfecta type II have been reported several times with ultrasonography. We recently experienced a case of osteogenesis imperfecta diagnosed in uterus by ultrasonogram and confirmed after termination and autopsy. We report here with a brief review of the literature.
