The predictive accuracy of the SRK II, SRK/T and Holladay formulas was evaluated in 22 eyes with sever myopia who had phacoemulsification and implantaton of posterior chamber IOL without suture. These patients were followed up for at least 6 months postoperatively. Correlation coefficient between the predicted refraction and actual refraction was 0.57(P<0.01) in the eyes using the SRK/T, 0.566(P<0.01) in the Holladay and (0.06(P=0.791) in the SRK II. The mean absolute error in the SRK/T 0.85 was smaller than that of the Holladay 1.04 and the SRK II1.08(p<0.05). The percentage of the eyes with absolute error within 1D was 68% in the SRK/T, 68% in the Holladay and 53% in the SRK II, but there was no statistically significant difference between them(p>0.05). The percentage of the eye with hyperopic shift(more hyperopic actual refraction than the predicted refraction) was 77% in the SRK II, 77% in the SRK/T and 86% in the Holladay, but there was no statistically significant difference between each formula(p>0.05). In conclusion, the SRK/T has the better predictive accuracy than the SRK II and Holladay in severe myopia and hyperopic shift tends to occur with the application of all three formulas.

The present studies were carried out, under natural room condition from June to July in 1969. The period required for growth of eggs and larva varied according to various temperatures and methods of rearing. The average number of eggs laid by the Culex pipiens pallens was 137 per egg raft. The period of gonotrophic cycle was from 3 to 6 days: incubation period of eggs was from 1.5 to 2 days: larva period was from 10 to 14 days: pupa period was from 2 to 3 days. Accordingly, the period from the beginning of gonotrophic cycle to the adult mosquitos in next generation required 25 days at the longest and 16.5 days at the shortest.

The short-term changes in corneal astigmatism and visual acuity after phacoemulsification with foldable intraocular lens implantation through a 3.2mm temporal clear corneal incision (group 1) and these through a 3.2mm superior scleral incision(group 2) were compared.Corneal topographic measurement were obtained preoperatively and at poeroperative 1 day, 2 months. Scalar and vector astigmatism in group 1 and group 2 were compared by simple subtraction method, Cravy method and Holladay method.The surgically induced astigmatism in both groups showed no difference in with-the-rule change(0.57D-0.10D) and uncorrected visual acuity also showed no different results in both groups. In the group 1, preoperative with-the-rule astigmatism were changed 0.18D toward with-the rule and preoperative against-the -rule astigmatism were shifted 0.64D toward with-the-rule direction.Conclusively. both incisions offered satisfactory short-term astigmatic results and rapid visual rehabilitation and change of astigmatism in the wyws with preoperative against-the-rule astigmatism was greater than those with peroperative with-the-rule astigmatism in temporal clear corneal incision group.

Acquired tufted angioma is a benign, slowly progressive angioma with a typical histological pattern that was first described by Wilson-Jones in 1976. We report a case of acquired tufted angioma in a 19 year old female who had erythematous papules and plaques on the right thigh. Histopathological findings showed multiple capillary lobules in a cannonball arrangement scattered throughout dermis, which was diagnostic of acquired tufted angioma.

Application of electric current in peritoneal dialysis was performed to observe the change of small intestine movement through an abdominal window, and to acceleration migration of certain ions. Prominent elevation of potassium in the dialysate was seen after applying a negative charge in the peritoneal cavity. N.P.H. was not much effected by introduction of the electric current. Acceleration of small intestinal movement was also observed after the application of electric current in peritoneal dialysis. Sow intestinal movement, when large amounts of lavage fluid are present in the peritoneal cavity, will be moderatelyaccelerated as a result of the application of electric current. Electric current can be applied both to prevent distension of the abdomen and adynamic ileus in peritoneal dialysis, and to accelerate too migration of the potassium ion and certain other ions.

Observation of intestinal movement in rabbits were performed through use of an abdominal window in peritoneal dialysis. The causes of an adequate drainage were also observed, through the abdominal window, and better drainage was obtained as a result of clear vision and catheter adjustment. Generally it was observed that the amount of small intestinal movement diminishes after dialysis solution was introduced into the peritoneal cavity, and the larger the amount of solution, the slower the small intestinal movement. The smaller dosage is better for effecting a diminished intestinal movement; however, the effect of the dialysis is not so great, because all the surface of the peritoneum can not be used. On the other hand, the larger dosage brings on a slowing down of the intestinal movement; yet its effect on the peritoneal dialysis is greater. Our observation lead us to conclude that 200cc of solution is more popular for rabbit experiment and that dosage above this should be avoided. Less influence to the small intestinal movement was noticed when the temperature of the solution remained a little higher than body temperature. The nephrectomized rabbits and the anuric rabbits show less intestinal movement than the normal rabbits. The possible causes of ilus and abdominal distension in peritoneal dialysis were noted and discussed. After giving prostigmin in dialysate the frequency of intestinal movement increased almost to normal. Judging from the result of this experiment, it is advisable to use small doses of prostigmin in dialysate routinely in peritoneal dialysis.

Condylomata acuminata are benign tumors which are mostly venereally transmitted. Common sites were coronal sulcus, perisnal area and prepuce. Among 28 patients, 21 acuminate lesions and 10 papular lesions were found. Twenty eight human genital warts in Korean were analysed by Southern blot hybridization. Sequences related to HPV6/11 are found in 89.3%(25/28) of the condylomata. HPV16 DNA was not found at sll. Subtype of HPV was determined by the restriction pattern of DNA cleaved with PstI restriction enzyme in 7 cases. Six cases of HPV6a and one case of HPV6c are found. The above results suggest that most of condylomata acuminata are caused by HPV6 and HPV11 in Korea.
