소금을 만드는 염전 결정지의 염도는 사해의 염분 농도와 비슷한데 이 염전에서 다양한 미생물이 발견되었다. 서해안에 위치한 한 염전의 결정지에서 박테리아는 1cc당 최고 2억 7천마리가 관찰되어 염전은 해양 미생물을 확보할 수 있는 좋은 환경임이 입증되었다.

The purpose of this study was to evaluate plasticizer pollution levels in mudflat solar salt, salt water and sea water of the nationwide saltpan. Also, it was analyzed the relationship between DEHP in solar salt and PVC mat following private period. DEP (ranging from 0.00 to 1.55 ppb), DIBP (0.00~2.38), DBP (0.00~4.90), DEHA (0.00~2.32), and BBP (0.00~1.45) in solar salt were shown a extremely low concentrations, and DEHP was present a concentrations ranging from 0.00 to 268.5 ppb in solar salt. Further, DMP, DPrP, DNPP, DNHP, and DCHP were not detected in all solar salt. Phthalate in sea water and salt water was present a infinitesimal amount levels. DEHP levels in sea water and salt water were not shown a high risk levels ranging from 0.00 to 3.4 ppb, and from 0.00 to 21.4 ppb, respectively. As expected in PVC mat of nationwide saltpan, the correlation between DEHP in solar salt and PVC mat private period showed a low positive correlation coefficient ($r^2$=0.0362).

This study was conducted to evaluate the heavy metal contents of mudflat solar salt, salt water, and sea water produced in the nationwide salt pan. In mudflat solar salt, moisture contents were significantly different (p<0.001) between regions, ranging from 7.357% to 14.862%. Arsenic (As) content ranged from 0.007 ppm to 0.497 ppm, cadmium (Cd) from 0.000 ppm to 0.101 ppm, plumbum (Pb) from 0.000 ppm to 0.191 ppm, hydrargyrum (Hg) from 0.006 ppb to 0.180 ppb, and copper (Cu) from 0.039 ppm to 4.794 ppm between regions, which were significantly different (p<0.001). Further, As, Cd, Pb, and Hg contents of sea and salt water were not in excess of their criterion points. Our results suggest that heavy metal contents of mudflat solar salt, salt water, and sea water produced in the nationwide salt pan were at safe levels. However, continuous management of heavy metal contamination, such as PVC met, is still necessary.

Magnesium has been used as parts of vehicles, case materials of notebook PC and mobile phone, and its demand has been increasing recently. Its extraction technologies were classified according to the two major reduction methods: the fused salt electrolysis and the thermal reduction method. A research on the extraction of magnesium from magnesite which has been being carried out at KIGAM was briefly introduced here. Magnesium was prepared using a fused salt electrolysis method through preparation of anhydrous magnesium chloride with lab scale experiments.

A 5-year-old male German shepherd dog was presented with a 4 day-history of anorexia and depression. Abdominal radiographs showed a large soft tissue mass and loss of serosal detail. Ultrasonographs revealed splenomegaly with the lacy pattern parenchyma, perivenous hyperechoic region at the splenic hilum, and loss of splenic venous flow. Computed tomographic findings included the enlarged non-enhanced spleen except perivenous region at the splenic hilum and a whirled soft tissue mass at the splenic hilum. Exploratory laparotomy confirmed the diagnosis of splenic torsion. Ultrasonographic findings including lacy appearance, hyperechoic perivenous echogenicity and absence of splenic blood flow and CT findings including no or minimal enhancement of the spleen and a whirled appearance of splenic pedicle could be useful for diagnosing isolated splenic torsion in the dog.

A 1.5-year-old, female domestic rabbit was diagnosed with uterine torsion accompanying hydrometra of the right uterine horn and pyometra of the left horn. The exploratory laparotomy revealed the torsion of bilateral uterine horns in the region of the uterine cervix. No growth was detected in fluid collected from the right horn of the uterus; however, Gram-positive micrococcus and bacilli were cultured from the left horn. The pathophysiology of the simultaneous occurrence of these disorders was suspected considering that abdominal distension progressed over 4 months and the rabbit's condition deteriorated abruptly within 2 days, hydrometra was the initial disease and then infection to the left uterine horn and torsion developed later due to the large volume of fluid within the uterus. This report is the first case showing uterine torsion accompanying hydrometra and pyometra in each uterine horn.

Omental torsion secondary to inguinal hernia has rarely been reported as a cause of acute abdominal pain. However, in our case, omental infarction due to prolonged inguinal hernia-associated omental torsion led to the formation of a large omental mass with marginal fibrosis, and the patient presented with chronic abdominal pain. A 74-year-old man presented with complaints of lower abdominal pain for 1 month; subsequently, bilateral inguinal hernias were identified through inguinal ultrasonography. CT scans revealed that the greater omentum was trapped within the right inguinal canal, leading to omental torsion. The greater omentum, distal to the pedicle, appeared as a 30 cm-sized oblong fibrofatty mass in the right lower abdomen and pelvic cavity. Laparoscopic omentectomy with hernia repair was successfully performed.

Intradural schwannoma accompanied with torsion is rare. Intradural lumbar schwannoma was found in a 63-year-old man presenting with right sacral pain radiating to the lower extremity. This mass showed minimal enhancement on MRI. The tumor's location changed each time on MRI and CT-myelography. The patient underwent surgical resection and the cauda equina, linked to this schwannoma, was severely twisted.

The torsion of the uterus is a rare gynecological emergency. It occurs mainly in the gravid uterus and extremely rarely in the non-gravid uterus. In this article, we report a case of a torsion of non-gravid uterus accompanied by a huge intramural leiomyoma with focus on CT and MR imaging findings.
