OBJECTIVE: In muscle and neuronal cells, calcium channels have been classified by electrophysiological and pharmacological properties into (1) voltage-dependent Ca2+-channel(1) P/Q-type Ca2+-channel (2) N-type Ca2+-channel R(3) L-type Ca2+-channel (4) T-type Ca2+-channel (5)R-type Ca2+-channel. The present study was done in order to investigate whether there is any difference in Ca2+-channel distribution between activated and normally fertilized embryos. METHODS: The immunocytochemical method was used to identify the existence of voltage-dependent Ca2+-channels in parthenogenetically activated 2-cell embryos by ethanol and SrCl2 treatment. These 2-cell embryos were obtained by exposure to 6% ethanol for 6 min and to 10 mM SrCl2 for 2h. RESULTS: P/Q-type Ca2+ channels and L-type Ca2+-channels have been identified. Whereas, three type of Ca2+-channel P/Q-type, N-type, L-type have been identified in 2-cell embryos fertilized in vivo. CONCLUSION: Activation by ethanol was faster than those by SrCl2. However, there was difference in DAB staining of the embryos between ethanol and SrCl2 treatment (87.7% and 54.1%). Intensity of staining was also different between ethanol- and SrCl2-treated group. However, it has not been known why there was some difference in DAB staining and staining intensity in the present study.

Poliovirus Sabin 1 strain has its own special features that make it a particularly attractive live recombinant mucosal vaccine vehicle. Sabin 1 cDNA was manipulated to have multiple cloning site and viral specific 3C-protease cutting site at the N-terminal end of the polyprotein, named RPS-vax system HIV-1 V3- and principal neutralizing domain (PND)-concatamers were successfully cloned into the multiple cloning site of the vector system and produced expected chimeric viruses by transfection of their RNA transcripts into HeLa cells. These chimeric viruses have shown to express introduced HIV-1 subgenome concatamers efficiently during their replication in the infected HeLa cells. Expressed proteins were confirmed to retain the wild type structures at least in parts. Replication capacity of the chimeric viruses was slightly lower than that of wild type Sabin 1 likely to be due to delay in processing steps during their replication. Differing from the virulent Mahoney vectors, the rec-Sabin 1 chimeric viruses maintained the foreign gene stably during the serial passages. These chimeric viruses have also shown to be able to induce specific humoral immunity to the introduced vaccine proteins when inoculated into the poliovirus receptor-expressing transgenic (Tg-PVR) mice. Antiserum obtained from the immunized transgenic mice showed to have neutralizing capacity to HIV-1 in vitro. These results strongly suggest that the chimeric viruses expressing HIV-1 vaccine epitopes can be used as a good live mucosal vaccine candidate against AIDS.

To investigate the maternal and child factors associated with early detection of cerebral palsy, 74 mothers of cerebral palsy children who were born since January 1, 1980 and being treated at Taegu Rehabilitation Center for the Handicapped, Rehabilitation Center of Taegu University, St. Paul Children's House and Pusan Welfare Association of Cerebral Palsy Children were interviewed from February to April 1987. There is no association between age of child when parents noticed the child's abnormality and educational level of father but it tend to be detected earlier when education level of mother is college or above compared with high school or under. There is a trend of earlier detection of child's abnormality although statistically not significant in case father is professional or managerial worker, monthly income of father is over 610,000 won, child is first-born, age of the parents is 34 years or under, child is a boy, and child has periodic well-baby check-up. The child's abnormality is detected earlier when mothers had 7 prenatal visits or more compared with those who had 6 visits or less (P<0.05). Parents noticed the child's abnormality first in 85.1% of the case whereas doctors detected it first in 2.7% and this percentage was not different whether the child had periodic well-baby check-up or not. The first physician's diagnosis of the children was cerebral palsy in 36.5% and the rest was normal, need for observation, uncertain, etc. Parents took the child to doctor for diagnosis 2-3 months after they noticed the child's abnormality and after the child was diagnosed as cerebral palsy parents either took no therapeutic measure or brought the child to physiotherapy or acupuncture or gave herb medicine before they started specific rehabilitative therapy. For early detection of the cerebral palsy children, teaching of evaluation method for child development should be reinforced both in medical school and clinical training course and should train the specialist for diagnosis and treatment of crippling conditions. Also, public education needed for the importance of early detection of crippling conditions and currently available methods for diagnosis and treatment.

Synovectomy of the knee in rheumatoid arthritis has been recommended as an effective procedure which improved symptoms such as pain, swelling, and limitation of motion. But some problems, such as limitation of range of motion, infection, long hospital days, occured in open synovectomy. Arthroscopic synovectomy yields reliable result compatible to open synovectomy with less invasiveness and postoperative morbidity. The authors analyzed 20 knees of 14 patients who has done synovectomy of knee in Kyung Hee University Hospital from September 1989 to October 1992. Of the 14 patients, thirteen were females and only one was male, ten knees were affected on the right and ten on the left respectively. Five knees were operated as open synovectomy and fifteen knees as arthroscopic synovectomy. In six patients, both knees were operated either open or arthroscopic synovectomies. The preoperative diagnosis of 20 knees were rheumatoid arthritis as clinically, serologically and radiologically, 13 knees are confirmed as pathologically. Average hospital days after operation were 19 days in open synevectomy and 11 days in arthroscopic synovectomy. Average operation time were 72 minutes in open synovectomy and 84 minutes in arthroscopic synovectomy. No complication occured as a result of these synovectomies. After average follow up of 19 monthes, 1 knee from 5 knees in open synovectomy and 3 knees from 15 knees in arthroscopic synovectomy had pain and intermittent swelling as postoperatively. And only 1 knee in open synovectomy had loss of range of motion. No other patients lost motion in their knees. Preoperatively 17 knees showed radiographic change of rheumatoid arthritis and 16 knees showed no progressive radiographic deterioration at final follow up. And patients overall showed a significiantly increased functional status postoperatively. In conclusion, the result obtained after arthroscopic synovectomy are comparable with those obtained after open synovectomy. In addition arthroscopic procedure had lessened postoperative morbidity as loss of range of motion, postoperative infection, long hospital days and useful as palliative surgery in advanced rheumatoid arthritis.
