Mammary carcinoma was induced in rats by itravenous injection of N-methy-N-Nitrosourea. Microangiography was perfromed to evaluate the microvascular alterations in mammary carcinoma after irradiation. The tumors were givena single dose of 1.400 rads using Co-60 telethrapy unit with field size of 4 x 4 cm at 40 cm SSD. The dose ratewas 147.5 rads per minute. Microangiography was performed prior to irradiation and at one, two, and four weeksfollowing irradiation. The results are as follows: 1. Before irradiation, mammary carcinoma in rats tended to formlobules and the basic vasculature consisted of peripheral vascular pattern with central penetrating vessels. Theperipheral vascular pattern was always richer than that of the center. Irregular and tortuous vessles stretchedfrom the periphery into the center of lobule. 2. One week following irradiation, an increase in the number ofsmaller, tortuous vessels and decreased intervasular distance were obseved in the central portion of each lobule.This finding seems to be due to an improved filling of some previously existing but unfilled vessels. This maylead to improved metabolic changes and reoxygenation. 3. Later's changes of microvasculature after irradiation aretortuosity, irregularity, narrowing, abrupt tapering, fragmentation, and extravasation. These findings progressedafter a lapse of time. 4. The results can be considered as the microangiographic demonstration of the fact that reoxygenation after irradiation is mainly due to dilatation of the collapsed tumor vessels.

A one step reverse transcription PCR (RT-PCR) combined nested PCR was set up to increase efficiency in the diagnosis of canine distemper virus (CDV) infection after developement of nested PCR. Two PCR primer sets were designed based on the sequence of nucleocapsid gene of CDV Onderstepoort strain. One-step RT-PCR with the outer primer pair was revealed to detect 10(2) PFU/ml. The sensitivity was increased hundredfold using the one-step RT-PCR combined with the nested PCR. Specificity of the PCR was also confirmed using other related canine virus and peripheral blood mononuclear cells (PBMC) and body secretes of healthy dogs. Of the 51 blood samples from dogs clinically suspected of CD, 45 samples were revealed as positive by one-step RT-PCR combined with nested PCR. However, only 15 samples were identified as positive with a single one step RT-PCR. Therefore approximately 60% increase in the efficiency of the diagnosis was observed by the combined method. These results suggested that one step RT-PCR combined with nested PCR could be a sensitive, specific, and practical method for diagnosis of CDV infection.

The present study was undertaken to evaluate the anthelmintic effects of fenbendazole against intestinal nematode; Ascaris lumbricoides, hookworm and Trichuris trichiura, and to compare the efficacy in fenbendazole, oxantel-pyrantel pamoate and placebo by means of double blind method. Out of 114 subjects harbouring Ascaris lumbricoides, hookworm and Trichuris trichiura, 36 cases were treated with single dose of fenbendazole, 38 cases with oxantel-pyrantel pamoate, and the remaining 40 cases had received the placebo. The results were as follows: In the group treated with fenbendazole (30-50 mg/kg), the cure rates were 83.9 percent in 31 subjects with Ascaris lumbricoides and 83.3 percent in 18 subjects with hookworm, and only 28.6 percent in 28 subjects with T. trichiura respectively. In the group treated with a single dose of oxantel-pyrantel pamoate (10 mg/mg), the cure rates were 96.7 percent in 30 subjects with A. lumbricoides, 95.2 percent in 21 subjects with hookworm, and 54.6 percent in 33 subjects with T. trichiura. Egg reduction rate was 85.7 percent in T. trichiura cases. On the other hand, the egg negative conversion rates in placebo group were 9.7, 8.3 and 33.3 percent in Ascaris, Trichuris and hookworm infections respectively. The above results showed that fenbendazole was highly effective against Ascaris and hookworm. However, incomparisom with oxantel-pyrantel pamoate, fenbendazole was less effective in regards of A. lumbricoides, hookworm and T. trichiura infections.

The idiopathic calcinosis of the scrotum (Shapiro, 1970) is usually multiple, asymtomatic nodules of the scrotal skin which begins m childhood or early adult life, increase in the size and numbers, and sometimes breakdown to discharge chalky contents. Clinically they are most often misdiagnosed as cysts. The forty eight years old male patient visited our hospital on Oct. 14, 1980, because of multiple asymtomatic scrotal masses which are pin head to walnut sized. There is no family history of calcification, scrotal or otherwise. Histology shows naked amorphous masses in the dermis without any evidence of residual cysts, and is acicular clefts in the masses. Most of the tumors were surgically removed in 5 sessions.

Gold preparation had been used frequently in the past in the treatment of rheumatoid arthritis, tuberculosis and lupus erythematosua, etc. It is still used. when other more potent remedies, such as steroid, failed. We report a case of drug eruption following the use of gold preparation. A 38 year-old female was referred to our department from orthopedic surgery because of generalized, multiple, pin head sized, violaceous and flat topped papules of 1 x 2 mm in size and mucosal erosions and ulcers following gold therapy for rheumatoid arthritis. She had received 5 intramuscular injections of gold preparation (Myochrysine'), 220mg in total amounts. Our clinical impression was lichen planus like drug eruption, but histopathological picture disclosed nonapecific dermatitis. The eruption had disappeared gradually following oral administration of antihistaminics and prednisolone and daily starch tub baths.

Choroidal metastatic carcinoma is very rare. We recently experienced a case of lung adenocarcinoma which presented to the clinic with ocular symptoms. This 57-year-old Korean male patient visited the department of ophthalmology due to decreased visual acuity and pain of the left eye. On MRI scan, a nodule was attached to the retina of the left eyeball. On simple chest radiograph, a large amount of pleural effusion was noted in the left pleural cavity. Emergency enucleation of the left eyeball was done with an impression of malignant melanoma causing an intractable ocular pain. Grossly, the lesion in the eyeball was rising from the choroid. On histologic examination, tumor cells formed many irregular, small gland-like structures. The tumor cells showed alcian blue-positive mucin in the cytoplasm and glandular lumens and were positive for CEA. Chest CT scan was performed postoperatively and showed a huge mass in the left lower lobe and multiple nodular opacities in both lung fields. Bronchoscopic biopsy revealed moderately differentiated adenocarcinoma similar to that of the eyeball.

Lichen sclerosus et atrophicus (LSA) is an uncommon condition of the skin with small white macular or atrophic plaques which predominantly affects the genital regions of middle aged and elderly women. We present an atypical case of LSA on a 58 year old woman. The patient had a brownish-black colored patch of 2.5 * 7.0 cm in size on the right clavicular area of one year's duration. The histopatholgy of the lesion disclosed classical findings of LSA. A marked incontinence of pigment is noted in the upper dermis which accounts for the clinical picture of the lesion. She was treated with topical hydrocortisone cream resulting in a marked diminution of pigmentation.
