5.Purification of r-Glutamyltranspeptidase from Rat Primary Hepatoma Tissue and Preparation of a Tumor Associated Antigen.
Yonsei Medical Journal 1988;29(1):37-48
r-Glutamyltranspeptidase (r-GT) from a rat hepatoma induced by 3'-methyl-4-dimethylaminoazobenzene (3'-Me DAB) was purified 833 fold. The purified enzyme had a specific activity of 15.0 U/mg protein with an overall yield of 3.8%. The molecular weight of native r-GT was estimated as about 350,000 daltons, whichs a multicomplex of a single polypetide having a M W of 59,000. Anti r-GT rabbit antiserum cross-reacted with kidney r-GT as well as liver r-GT. Tryptic digestion of r-GT followed by separation with Con A sepharose column chromatography resulted in two major glycopeptides. A tumor associated antigen was prepared by the conjugation of a tryptic glycopeptide of r-GT to keyhole limpets hemocyanin and an antibody against this antigen cross-reacted preferentially with r-GT in rat hepatoma tissue.

The antihypertensive effect of captopril was evaluated in 15 patients with mild to moderate essestial hypertension(Mean age : 55, Mean blood pressure : 171/102mmHg). Captopril was administered 25 to 50mg twice daily with or without hydrochlorothiazide by mouth according to our protocol which was presented in the text. All the patients were followed up to 12 weeks. Captopril with or without hydrochlorothiazide significantly lowered the systolic and diastolic pressure in almost all patients. The mean systolic and diastolic pressure were reduced to 134/86mmHg(-37/-16mmHg ; -22/-16%)(p<0.001). Heart rate did not change significantly. No unwanted effects were observed. We conclude captopril has exellent antihypertensive effect in most patients with mild to moderate essential hypertension.

The increasingly successful results of hair restoration surgery in the last years have developed the interest and the confidence of patients and it is the most frequently performed esthetic surgery among male patients. Currently, various kinds of techniques for hair restoration surgery including hair transplantation, scalp reduction, and scalp flaps are performed in our clinic. Among these, hair transplantation is the basic and the most popular procedure, which can be performed not only by itself but also in conjunction with other procedures. 123 consecutive cases of hair transplantations were peformed from Jan. 1995 to Feb. 1996 for male pattern baldness, traumatic alopecia, and female pattern baldness under out patient base. The authors introduced a new classification for male pattern baldness, which are the type M, O, C, U, M-O, and C-O after alphabet to make simple and easy for clinical application. The ancillary procedures were scalp reduction, preauricular flap, and scalp expansion. An ellipsis of hair bearing scalp taken from the occipital area was sliced into slit-, mega-, mini-, and micro-grafts. The survival rate of the grafts was over 90% with minimal complications. This hair transplantation technique enabled us to achieve a good density and more natural looking hair with avoidance of cobble stoning and apparent scar.

Various surgical methods have been used to reconstruct severe soft tissue defects of the finger with exposed critical structures such as tendon, bone, and nerve. Some of these methods include rotation flap, cross finger flap, or regional flap similar to neurovascular island flap. However, there were often difficult situations where a flap could not be applied depending on the remaining surrounding tissue, injured area, and size of defect. As a result, free flap or distant flap may become necessary. However, distant flaps often cause stiffness of the finger joints since the hands need to be immobilized for a long time, while standard free flaps may be too thick to cover the finger and cause problems such as morbidities of the donor site. Since May, 1997, at Anam Hospital, we have performed reconstruction on 6 patients with soft tissue defect using a thin, flexible medial plantar septo-cutaneous free flap similar to the volar aspect of the finger in anatomical characteristics of the skin and subcutaneous tissue covering. The vessels used for this flap were superficial branches of medial division of the medial plantar artery and vena comitantes, or the subcutaneous veins. The mean size of the flaps was 2.75cm x 4.25cm. Primary repair or split-thickness skin graft was performed on the donor site depending on the size. All the flaps survived without significant complications, except one case of venous insufficiency. The composition of the transferred flaps was good with the recovery of pain, touch and temperature sensation. A free medial plantar septo-cutaneous flap has several advantages, e.g., it is small in comparison with other standard free flaps, having two draining venous pathways, good color and texture, and a good recovery of protective sensation. This flap can be used for the reconstruction of soft tissue defect on the heel and foot, as well as the volar aspect of fingers.
