Alteration in the hormone level associated with menstrual cycle influences the interaction between the urethra and bladder as well as detrusor function, maybe due to the common embryological origin of lower female genital and urinary tract. We tried to investigate the effect of the menstrual cycle on cystometric diagnosis through this retrospective study. 60 women with regular menstruation were enrolled in this study. The study groups were divided into 2 groups, Group I was women whose symptoms were not influenced by the menstrual cycle, Group II was women whose symptoms were adversely affected premenstrually. The majority of normal cystometric diagnosis were made in the luteal phase (Group I: 42.9% vs 4.4%, p<0.05; Group II: 50.0% vs 22.2%, p<0.05). But diagnosis of genuine stress incontinence, detrusor instability, mixed genuine stress incontinence and detrusor instability were frequently made in the follicular phase of mentruation. Normal cystometric diagnosis in the group II were more commom than the group II ( 36.8% vs 19.7%, p<0.05 ). The results of this study reveal that the timing of cystometric evaluation may influence the the detection of a positive diagnosis. In patients whose symptom are influenced by their menstrual cycle, the luteal phase may not be the correct time to make an accurate diagnosis.

Epidermal growth factor(KGF) and transforming growth factor arpha(TGF-a) are polypeptides of 53 amd 50 amino acid residuies. Both bind to epidermal growth factor receptor (EGR-R) leading to phosphorylation of the receptor, enhancement of its tyrosine-specific kinase activity and ultimately to stimulation of cell growth. To study he role of EGF, TGF-a, and EGF-R in differentiation and hyperproliferation of cell, we se lected psoriasis vulgaris, because the affected keratinocyte may house both an abnormally increased proliferative capacity and an abnormally differentiated state. The biopsy specimens were taken from involved and uninvolved skin of 20 patients with psoriasis and immunoperoxidase studies with formalin-fixed paraffin-embedded tissues were performed with EGF, TGF-a and EGF-R useing the Vectastain ABC irnmunoperoxidase stain system. The antibodies were used at a concentration of 6 ug/ml In involved psoriatic skin, distributions of TGF-a and EGF-R were increased in all layers of epidermis as compared to normal, uninvolved psoriatic skin, in which chev were showed to the basal and parabasal layers. However, distribution of EGF was weekly positive in the basal layers of epidermis in both involved and uninvolved skin with no difference between toem. These results suggest that increased distribution of TGF-a and EGF-R may be involved in hypoproliferative state of epidermal keratinocytes in psoriatic lesion.

Transglutaminase(TGase) is a calcium dependent enzyme that catalyse and acyl transfer reaction forming epsilon-(gamma-glutamyl)-lysine cross linkage. the major known effect of TGase is its important role in the programmed cell death manifested in the granular layer of the skin and acidophilic bodies in the viral hepatitis and neoplastic processes. The enzyme activity, immunohistochemical reaction using polyclonal antibodies against cytosolic TGase C, light and electron microscopic studies and TdT staining of the transplanted fibrosarcoma cells in C3H mouse with radiation therapy were done. The presence of TGase was detected immunohistochemically by avidin-biotin peroxidase complex (ABC) method Apoptosis were significantly induced after irradiation dependent with time factors and irradiation doses, resulted in marked and confluent tumor cell loss. Highest activity of the cytosolic form of TGase was noted at 24 hours and decrease after then while membrane bounded form of the TGase showed no significant changes. Immunohistochemical staining revealed strong positive reaction in the sarcoma cells in diffuse fasion and around the necrotic foci in the cytoplasm. Terminal dideoxynucleotidyl transferase(TdT) staining revealed increasing numbers of apotptic cells from two hours after irradiation. In the mechanism of decreasing tumor size and cell death in radiation therapy, apoptosis plays an important role and during that process transglutaminse might do some irreversible cross-linking effects of cytoplasmic proteins causing cell death in part.

Tuberculosis of the puboischium is an uncommon entity. The two constant features in tubereulosis of the pubis are limping and abscess formation. This disesse should be differentiated from other diseases such as osteitis pubis, suppurative osteomyelitis, postpartum synphysiolysis, and adolescent osteochondritis. Kirker advocated that wide excision of the lesion for the treatment of this disease is the best method. However, Nicholson(1953) reported that the lesion has a good prognosis snd responds well to simple curettage. Since the first reports by Thilesen(1855) and by Heinnies(1888), there were paucity of reports. Also in Korea, there have been no report about this disease. The five patients who were treated at the Ksng-Nsm St. Marys Hospitsl between 1982 and 1987 were reported. The results were as follows ; 1. Four patients were boys and one was a female. 2. All cases had clinically abscess, tenderness at the lesion, and limp. 3. Lesions in four cases responded well to simple curettage and18 months of chemotherapy. However, in one case fusion of the symphysis using a plate was performed because of tuberculosis-induced instability of the sacroiliac joint. 4. In a child, destroyed symphysis pubis was well restituted after treatment. Through the cases it is concluded that simple curettage and anti-tuberculous chemotherapy are good treatment modality for tuberculosis of the puboischium.

Flowcytometry is a very important technique for the analysis of cell properties, with the advantages of simultaneous multiparameter analysis of large cell population in a short time. Recent advances in computer science and techniques in cell preparation and staining make it more valuable for the study of cell biology and its clinical application. This study was performed to establish the techniques of flowcytometry analysis of osteosarcoma cells, to evaluate the results of the characteristics of the DNA and specific cell cycle phase of osteosarcoma cells obtained by preparation of paraffin-embedded tissue blocks, and to analyze any possible difference between cell populations lacated apart from each other in the tumor mass for making a base for further clinical application. Paraffin-embedded tissue blocks were obtained from 10 cases of primary osteosarcoma, which had undergone amputation without chemotherapy or radiotherapy. Tissue blocks obtained from the most superficial and the deepest portions of the tumor mass from the skin surface were selected respectively in each cases. To evaluate the technique and results obtained, analysis of the whole sample were performed twice in a separate setting. Satisfactory DNA histogram was obtained from 14 of 20 tissue blocks, with the values of distribution in the specific cell cycle phases. DNA aneuploidy was found in 2 cases with a DNA index of 1.6 and 1.3, and no difference in DNA ploidy by the location in tumor mass. The S-phase and G2+M phase fraction were 13.2±8.5 and 6.2±3.1 respectively, reflecting the increased cell proliferation compared with normal cell population. There was no statistically significant difference of these values between superficial and deep portions, but the difference was 9.0±9.7 with a maximum of 26.6, much greater than the difference 3.3±3.6, between the first and second set of analysis. Flowcytometry is a very useful technique in the analysis of the DNA and cell cycle phase properties, and the characteristics of DNA and cell proliferation status of osteosarcoma cells were successfully evaluated by this technique. Unsatisfactory DNA histograms were thought to be the result of inappropriate samples. To adequately evaluate the changes in the tumor mass, standardization in obtaining tumor tissue about the location in the tumor mass is suggested for future studies with flowcytometry about the properties of tumor cells.
