OBJECTIVE: This study is to investigate the clinical efficacy of low-dose FSH regimen, comparing with clomiphene citrate and human menopausal gonadotropin (CC/hMG) regimen. METHODS: Retrospective study of the ovulatory factor infertility 39 patients who had been treated by intrauterine insemination (IUI). The 31 cycles of 21 patients were stimulated by CC/hMG regimen, the 22 cycles of 18 patients were stimulated by low-dose FSH regimen. We compared the rate of clinical pregnancy, multiple pregnancy and ovarian hyperstimulation syndrome (OHSS) of both group. RESULTS: The rate of clinical pregnancy of the CC/hMG group was 25.7% per cycle, and that of the low-dose FSH group was 54.5% per cycle. The low-dose FSH group showed a higher rate of clinical pregnancy per cycle than CC/hMG group (p=0.028). However, no differences was found statistically in the rate of multiple pregnancy and OHSS between CC/hMG group (22.2%, 5.7%) and low-dose FSH group (33.3%, 13.6%). CONCLUSION: This study showed that the low-dose FSH regimen is superior to CC/hMG regimen in getting clinical pregnancy, but dose not reduce the ovulation induction complications.

I tried the endoscopic laser therapy for the malignant and benign disease of the alimentary tract to evaluate efficacy in rejection of surgical treatment or inoperable state. I have experienced 16 cases of the laser therapy in my hospital from July 1990 to June 1991. The apparatus I used is the SLT contact Nd-YAG laser with the ceramic endoprobe of rounded or chisel or hollow type in each case. The irradiation was made at an output of 15-20 Watts within 1.5 seconds. Between the 2-4 weeks laser therapy, the treatment response was observed by rebiopsy, I treated 7 cases of early gastric cancer and post-laser follow-up study showed 70% negative for cancer cells by endoscopic biopsy. Failure of laser treatment was found in case of IIc type, Two cases of advanced gastric and I case of rectal cancer with severe obstruction were relieved by laser therapy. I also experienced 3 cases of esophageal or gastric polyp which were completely. resolved after irradiation. Besides, I could get hemostasis in 1 case of gastric ulcer bleeding with exposed vessels and 1 case of Mallory-Weiss syndrome. And a case of gastric bezoar was completely fragmentated after irradiation. As mentioned above, I achieved satisfactory results of 13 cases in 16 cases. Contact Nd - YAG laser treatment ean be applicated with excellent efficacy in any age, sex and severity of disease with or without complications and any site of lesions which can be reached within the endoscope. I suggest it is maybe highly promising medical technique in the future.

BACKGROUND: Although there were many studies about increasing the bone mineral density(BMD) of the elderly by exercise program, the results of weekly exercise participation degree are still to be not prepared. Therefore I examined that the effect of weekly exercise participation degree on BMD level of the elderly. METHODS: Subjects were 93 older adults (male=43, female=50) residing in Seoul-Seniors-To-wei. These people are either participating in exercise program for a year, or not in Song-Do Hospital Exercise Prescription Center. Among the elderly, if one were took part in exercise program 5 days or more weekly, they are classified in Group A(male = 14, female= 14), if one were took part in exercise program 5 days weekly, they are classified in Group B (male = 14, female = 17), if one were took part in exercise program a day weekly. they are classified in Group C(mal =8, female= 13). and if one were not took part in exercise program, they are involved in Group I)(male=7, female=6). All the measured data were represented by mean and standard deviation using SPSS package(ver10.0). The statistical techniques for data analysis of BMD levels of the four groups in male and female groups were to analyze the differences among groups by one way ANOVA. And then I performed the Scheffe post-hoc method forinvestigating exactly the differences among groups. The 5% level of significance was used as the critical level for acceptance of hypotheses for the study. RESULTS: There were no statistical difference (p>0.05) among four male or female groups in BMD levels of head, anus, trunk, ribs, and pelvis parts. But there were statistical differences(p <0.05) among four male or female groups in BMD levels of legs, spine, and total. On the condition of legs, the BMD level of Group A exercised in 5 days or more weekly was 1.58 g/cm2 (F=6.774, p=0.001) in male groups and 1.17 g/cm2 (F =6.616. p=0.001) in female groups. These levels were the highest among four groups. And on the condition of spine, the BMD level of Group A was 1.17 g/cm2(F=7.732, p=0.001) in male groups and 1.16 g/cm2(F=6.243, p=0.002) in female groups. These levels were the highest among four groups. Also on the cutiditiuii of total, the BMD level of Group A was 1.53 g/cm2(F=5.677, p=0.003) in male groups and 1.1 g/cm(F=5.283, p=0.003)in female groups. These levels were the highest among four groups. CONCLUSION: Although the exercise is advantageous to the elderly people, if they are participated in 5 days or more weekly, they will be gained more benefit on BMD level and so on.

Although arthroscopic surgery has been used conventionally, it has not been widely adopted yet due to the risks of complications, including nerve damage, technical difficulties, and limited indications. As shown in other joints, however, the use of an arthroscope will gradually increased in the elbow joint (‘Arthroscopy always wins’). Herein, arthroscopic treatments and arthroscopic ulnar nerve decompression will be discussed in cases of elbow osteoarthritis.

To develop the polymerase chain reaction (PCR) for the detection of type D simian retrovirus (SRV) infection, an oligonucleotide primer pair was designed to hybridize to the sequences within euv gene of SRV subtype 1 (SRV-1). The 3'proximal env sequences annealing to the primers had been rather conserved among three different subtypes of SRV, SRV-1, SRV-2, and SRV-3 (Mason-Pfizer Monkey Virus: MPMV). The PCR using the primer pair targetingan an env region the successfully detected and amplified all three subtypes of SRV with excellent specificity after single round of reaction. The tests with peripheral blood mononuclear cells infected either with simian immunodeficiency virus or simian T-lymphotropic virus type 1, maior immunosuppressive viral agents together with SRV in simian, verified the specificity of the PCR by excluding any cross reactivity. Semiquantitative titration PCR, amplifying serially diluted plasmid DNA of each subtype, was performed to evaluate sensitivity limits of the reaction. Based on molecular weight of each cloned SRV genome, the PCR should be able to detect one SRV-infected cell per more than 5-7x104 uninfected cells after simple ethidium bromide staining of resulting products. The PCR must be very efficient screening sisters with its quickness, certainty, and sensitivity for SRV-infected animals used in human AIDS research model. Second round amplification of the reaction products from the first PCR, or Southern hybridization by radiolabeled probes shall render to compete its efficacy to ELISA which has been the most sensitive technique to screen SRV infection but with frequent ambiguity problem.

Indications of reverse total shoulder arthroplasty (RTSA) have been consistently extended by technical advancements in reverse arthroplasty prosthesis, continuous development of the implants, accumulated experiences and its successful treatment outcomes; accordingly, its use has rapidly increased. RTSA has been performed for a variety of indications, with variable outcomes depending on the initial diagnosis. However, controversial opinions still exist regarding the design of reverse arthroplasty prosthesis (medialized or lateralized design and the neck-shaft angle of the humeral prosthesis), suture of the subscapularis tendon, use of cement during placement of the humeral prosthesis, and surgical procedures; therefore, these should be investigated so that they can be better understood.
