Recreational diving is an exciting and adventurous sport, but is also potentially hazardous. Despite its inherent hazards, an increasing number of people enjoy SCUBA (self-contained underwater breathing apparatus) diving; the number of diving-related accidents is therefore also likely to increase. Divers might face physical or psychological stresses from the unfamiliar or hostile underwater environment, which can lead to fatal accidents. To investigate deaths related to SCUBA diving, a forensic pathologist should understand the types and mechanisms of injuries and illnesses unique to SCUBA diving. Postmortem examination of diving fatalities is therefore a formidable task for most forensic pathologists because cases are sparse and the process requires an understanding of diving physiology, diving equipment, and the underwater environment. The primary aim of autopsies in SCUBA diving fatalities is to detect evidence of pulmonary barotrauma, intravascular gas, or pre-existing illnesses. Standard autopsy protocol for SCUBA diving-related deaths should include methods to detect intravascular gas and gas accumulation in the tissue or body cavity through plain radiographs or Computerized Tomography (CT) scans. Analysis of the gas components is also helpful for determining the origin of the gas. Here, the author proposes a practical method for performing an autopsy on a person who died while SCUBA diving.

Heterotropic ossifications have been known to occur around joints in many pathological conditions of the nervous system mostly in paraplegia and is affects most of the hip joint. Recently, 4 cases of heterotropic ossification in 18 cases of traumatic paraplegia have been reviewed at the orthopedic department of Kyungpook National University Hospital from April 1965 to July 1968 and the results obtained were as follows: 1. All cases were found in male of 3rd to 4th decade. 2. Heterotropic ossification affectected around the hip joint in 3 cases and in the other one case around the medial femoral condyle of knee joint. 3. Three cases affecting around hip joint expressed pressure sores on ipsilateral great trochanteric area, but the other one case affecting around medial femoral condyle had not any pressure sore. 4. In all cases, the heterotropic ossification was noted on X-ray film within 4 to 6 months after paraplegia.

In this experiment 40 adult male C57BL mice were used. The one ear of each animal was irradiated with high pressure mercury lamp (Burdick'UV-800) and the other ear was covered with nontransparent tape. Using split epidermal sheets treated with DOPA solution, a quatitiative study of epidermal melanocyte was carried out from the exposed and the shielded ear continuously on every second day during 14 daily exposures to 100 mJ/cm of UVB. The results were as follows : 1. Repeated radiation with ultraviolet light elicited a significant increase in population of melanocytes and the possible mechanism is a direct replication of the functioning melanocytes. 2. UVB irradiation induced increase in the number of epidermal melanocytes in covered ear as well as in irradiated ear. It is suggested that the population increase in the shielded skin is initiated by one or more systemic factors originating from the UVB irradiated skin.

1)The oxygen consumption was studied with albino rate under normal environment after they were given Cytochrome C intravenously (10mg/kg). The consumption was 74.6cc/kg min. with that of control, 75.4cc/kg. min. The difference of the consumptions was not statistically significant. However, under 0.5% CO environment, the oxygen consumption of the Cytochrome C treated rats (62.5cc/kg min) was significantly greater than the control(42.1cc/kg min.) 2) The recovery time of rat acutely poisoned by 1% CO was studied. The recovery time of the Cytochirome C treated group was 37.2 minutes and in control group it was 52.2 minutes. Also significant difference of fatality was noted between the treated group(21.8%) and the untreated group(49.7%). 3) The combined effects of the hyperbaric oxygenation (100% O2 at atmospheric pressures) and the Cytochrome C administration was compared with the effect the simple hyperbaric oxygenation. There was no significant difference of recovery time between the experimental group while the fatality of the experiment group was lower than control group.

Compared with the antipsoriatic retinoid etretinate, the new aromatic retinoid ar, itretin represents an important, advance due to its rapid eliminatian kinetics. Therefore acitretin treatment may represent an important alternative to etretinate in females of childbearing potential. From recent clinical studies it appears that acitretin and etretinate have similar therapeutic effectiveness in severe poriasis including generalized putular psoriasis and psoriatic erythroderma. We preset a case of generalized pustular psoriasis in a 18 year old female who was treated successfully with aritretin. She had generalized pustular eruptions on erythematous base associated with high fever and chills. With the administration of acitretin at a dose of 30mg/day, marked improvement was achieved.

Cholelithiasis and cholecystitis frequently necessitate cholecystectomy. Experience is increasing with laparoscopic cholecystectomy, a technique that avoids much of the morbidity, pain, prolonged hospital day, and recovery complications associated with the traditional approach. And the safety of laparoscopic cholecystectomy was confirmed. Besides appendectomy, cholecystectomy is the second most common nonobstetric procedure performed in pregnant women. We have performed one case of a successful laparoscopic cholecystectomy in the second trimester of pregnancy. Pregnancy was once a contraindication of laparoscopic operation, but no longer.
