1) The patient was a male aged 20 years who has an intermittent exophthalmos of the left eye when he bend a head forward. 2) Exophthalmometry reveals OD: 11 mm OS: 17.5 mm by Hertel method base 96 in bend forward position. 3) The disc of the left eye was a slight discoloration and no changes whether protrusion of the eye or not. 4) It may be caused by varix of the left orbital vein examined by skull X-ray, optic foramen, Water's view and carotid angiography. 5) Vision OD: 1.0 OS: 0.4.

DNA aneuploid cells are poorly characterized in both biochemical and morphological terms. This study was performed to see the relationship between DNA ploidy and morphometric and photometric nuclear features. DNA contents of tumor cells were measured by image cytometry in 46 cases of micro- or early invasive squamous cell carcinoma of the uterine cervix. Also measured were nuclear area, perimeter, maximum diameter, chromatin pattern index, and staining intensity. Among the 46 cases, 20 cases which had both DNA diploid and aneuploid cell subpopulations were selected, and the two subpopulations were discriminated statistically. Multivariate discriminant analysis seperated clearly the two subpopulations, whereas univariate analysis failed. For canonical discriminant function, nuclear area was selected first, followed by staining intensity in each case. Other variables selected afterwards were nuclear perimeter, maximum diameter, and/or chromatin pattern index in random fashion. Correlation coefficient between the canoncial discriminant function and the variables were 0.20~0.40 for nuclear area and 0.25 or less for the others. The above results suggest that DNA ploidy is a parameter more or less independent on individual morphometric and photometric parameters.

MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) is one of the mitochondrial encephalomyopathy, A rare disease caused by a disturbance of the mitochondrial chain of respiration. MELAS is confirmed by typical light and electron microscopic findings : "ragged red fibers" by modified Gomori trichrome stain on light microscope and numerous abormal mitochondria on electron microscope. We experienced a boy with the characteristic clinical and pathologic findings of MELAS. Our patient demonstrated bilateral basal ganglia calcifications and infarction at right parieto-occipital and thalamic areas on CT and MR We found that MRI was more sensitive and represented the infarcted lesions better than CT. Detection of cerebral insults of MELAS by MRI is important in making decision on patient treatment and also in predicion of the patient prognosis.

The medial collateral ligament is the most commonly injured ligamentous structure of the knee and it has been demonstrated that this ligament is the prime static stabilizer of the medial side of the knee joint. The management of the medial collateral ligament injuries were divided into surgical and conservative treatment. Many investigators reported consistently good to excellent results following surgical treatment. More recently, other investigators reported that isolated medial collateral ligament injuries did equally well under non-operative as operative treatment. For accurate diagnosis, arthroscopic examination of the knee to rule out other intraarticular pathologic conditions such as cruciate ligament injuries, maniscal tears and bony injuries is essential. From October 1988 to January 1991, we treated 76 cases of isolated medial collateral ligament injuries which was confirmed by diagnostic arthroscopy. Among them, we analyzed 31 cases that minimum follow-up was over 1 year and could be re-examed, 20 cases were treated with surgery and 11 cases were not. With comparision between initial and final follow-up stress X-ray, 5.45 ± 3.17mm in non-operative group had improved in medial laxity(P < 0.05). The Marshall scores which checked at final follow-up, averaged 40.3 ± 7.299 in operative and 37.364 ± 6.485 in non-operative group (P>0.05). In conclusion, medial stability was improved in operative than in non-operative group, however functional score was equally well under non-operative as operative treatment.
