1.Incidence of parasites found on vegetables collected from markets and vegetable gardens in Taegu area.
The Korean Journal of Parasitology 1972;10(1):44-51
A parasitic survey on vegetables collected from markets and vegetable gardens in Taegu area was conducted for the discovery of human parasitic eggs and larvae. Three species of vegetable, lettuce (Lactuca sativa), young radish(Raphanus sapivus) and Chinese cabbage (Brassica pekinensis) were selected. All vegetable leaves were washed with a hard brush, and then species of parasites and the approximate mean number of parasitic eggs per 200 grams of vegetable leaves were investigated. When vegetables collected from markets were examined, 5 species of parasite eggs (ascarid, trichurid, Trichostrongylus, Clonorchis and hookworms) and 2 larvae (filariform and rhabditoid ) were found. Furthermore, a number of eggs and larvae of undetermined species were also observed. Of the parasites studied, ascarid egg was found to be highest (49.0%), followed Trichostrongylus egg(18.0%) as well as filariform larva of hookworms (19.7%), and the least often observed was rhabditoid larva of hookworms(0.7%). The recovery rate of parasites among lettuce, young radish and Chinese cabbage collected from markets ranged from 23.2 to 91.9 percent and was similar to that from vegetable gardens, where Chinese cabbage showed the highest (91.1%) and lettuce being next(49.0%) in positivity of ascarid eggs. In the case of filariform larva, the rate of Chinese cabbage was twice as high as that of lettuce and young radish. There was a significant reduction in the rate of filariform larva, suggesting that a single washing of vegetables at the vegetable washing stand would reduce the number of parasites attached to vegetable leaves, when young radish washed at the stand was compared with that unwashed. In the monthly rate of parasites recovered from young radish, there was significant fluctuations between the eggs and filariform larva of hookworms. The mean number of ascarid egg per 200 grams of vegetable was 7.5 in young radishes, 3.1 in lettuces, and 0.5 in Chinese cabbages, in decreasing order. It is noteworthy that young radish contained more than 10 times more than Chinese cabbage. These results would seem to indicate that one of the important routes of infection is due to consumption of pickled young radishes in summer than pickled Chinese cabbages in winter.

The Journal of the Korean Orthopaedic Association 1984;19(3):472-482
During the period of 25 years from Apr. 1959 to Jan. 1984, 58 patients of non-tuberculous infec-tion of the spine (53 pyogenic osteomyelitis and 5 iatrogenic and primary discitis) were admitted and treated at our department. Clinical analysis was carried out following results were obtained. 1. The incidence was higher in the 3rd and 4th decade and the sex ratio between male and female was 2.1:1 2. The relative frequency of the commonly involved sity were lumbar(60), thoracic(17.), cervical(9%), lumbosacral(7%), thoracolumbar(3.5%), cervicothoracic(1.5%), in that orders. 3. The morbidity period less than 1 month was only in 22% and that less than 1 year was only 4. The frequent clinical symptoms and signs were back pain(91), tenderness(88%), muscle spasm (76%), and fever and chillness(41%). 5. The causative microorganism was identified in 43 cases among which 77% was coagulase positive staphylococcus. 6. Expected spontaneous bony fusion was not found in any case of 9 follow-up cases of conservatively treated group, while excellent bony union was noticed in all 16 follow-up cases of anterior fusion group except one. 7. Anterior spinal fusion seems be to indicated in those cases such as with failure of conservative treatment, paraplegia, concomitant mechanical instability, long duration of sinus tract and even with dubious bacteriological diagnosis. 8. Anterior spinal fusion for pyogenic osteomyelitis and discitis has the advantages, that is eradication of diseased foci with easier bacteriological diagnosis, cord decpmpression, increase of bony stability, and promotion of bony union. 9. Laminectomy was indicated in those cases with epidural abscess. 10. Bone scan and computed tomography were useful in the early diagnosis and evaluation of treatment results.

6.The anti-tubercular activity of Melia azedarach L. and Lobelia chinensis Lour. and their potential as effective anti-Mycobacterium tuberculosis candidate agents
Asian Pacific Journal of Tropical Biomedicine 2016;6(10):830-835
Objective: To evaluate the anti-mycobacterial activity of Melia azedarach L. (M. azedarach) and Lobelia chinensis Lour. (L. chinensis) extracts against the growth of Mycobacterium tuberculosis (M. tuberculosis).
Methods: The anti-M. tuberculosis activity of M. azedarach and L. chinensis extracts were evaluated using different indicator methods such as resazurin microtiter assay (REMA) and mycobacteria growth indicator tube (MGIT) 960 system assay. The M. tuberculosis was incubated with various concentrations (50–800 mg/mL) of the ex-tracts for 5 days in the REMA, and for 4 weeks in MGIT 960 system assay.
Results: M. azedarach and L. chinensis extracts showed their anti-M. tuberculosis ac-tivity by strongly inhibiting the growth of M. tuberculosis in a concentration-dependent manner in the REMA and the MGIT 960 system assay. Particularly, the methanol extract of M. azedarach and n-hexane extract of L. chinensis consistently exhibited their effects by effectively inhibiting the growth of M. tuberculosis in MGIT 960 system for 4 weeks with a single-treatment, indicating higher anti-M. tuberculosis activity than other extracts, and their minimum inhibitory concentrations were measured as 400 mg/mL and 800 mg/mL, respectively.
Conclusions: These results demonstrate that M. azedarach and L. chinensis extracts not only have unique anti-M. tuberculosis activity, but also induce the selective anti-M. tuberculosis effects by consistently inhibiting or blocking the growth of M. tuberculosis through a new pharmacological action. Therefore, this study suggests the potential of them as effective candidate agents of next-generation for developing a new anti-tuberculosis drug, as well as the advantage for utilizing traditional medicinal plants as one of effective strategies against tuberculosis.

The aim of this study was to clarify the role of Kupffer cells in the mechanism of endotoxin-induced liver injury. The study on fine structure of Kupffer cells was performed after the injection of endotoxin. The endotoxin(Escherichia soli lipopolysaccharide 026: B6, 1.5mg/100 g of body weight) was intraperitoneally injected in Sprague-Dewley rats. Animals were sacrificed at 1/4, 1/2, 1, 2, 4, 8, 16, 24, 72 and 120 hours after the injection of endotoxin. Livers were extirpated and processed to be examined by light and electron microscopy. The results obtained were summerized as follows: Early changes observed in liver after endotoxin injection included the increased number and hypertrophy of Kupffer cells, infiltration of neutrophils and presence of fibrin thrombi within the sinusoids. The coritinuous increase of the Kupffer cells in number with hypertrophy, congestion and infiltration of inflammatory cells within the sinusoids were observed. Hepatocytes showed* fatty change and occasional necrosis. At 72 hours the congestion decreased. At 120 hours the number of Kupffer cells was increased, but the morphology of Kupffer cells became similar to that of the control group. The numbers and sizes of primary and secondary lysosomes and amount of euchromatin of Kupffer cells increased. Swellings and increase in number of mitochondria, Golgi complex, smooth endoplasmic reticulum, rough endoplasmic reticulum were evident. Microthrombi were present within the sinusoids. The swelling of rough endoplasmic reticulum and mitochondria, decrease of glycogen particles, fatty change, hypoxic vacuoles, pyknotic nuclei and occasional necrosis were observed in hepatocytes. At 72 hours the number of secondary lysosomes in Kupffer cells decreased. At 120 hours the morphology of Kupffer cells became similar to that of the control group. According to these results, it was postulated that the endotoxin was initially taken up by pinocytosis into Kupffer cells and degraded in secondary lysosomes of activated Kupffer cells. Kupffer cells may play an important role in the defense mechanism of liver during endotoxemia. The dysfunction of Kupffer cells and ischemia by sinusoidal microthrombi may cause liver injury.

To investigate the immunohistochemical expression of mutated p53 protein and bcl-2 protein in the cutaneous melanocytic lesion, 15 cases of compound nevus, 10 cases of congenital melanocytic nevus, 15 cases of primary malignant melanoma(4 cases less than 1.5 mm thick and 11 cases more than 1.5 mm thick), and 10 cases of metastatic malignant melanoma(7 cases in lymph node and 3 cases in soft tissue) were examined. All cases of compound nevi and of congenital melanocytic nevi showed no immunoreactivity for p53 protein. p53 protein overexpression was observed in 75%(3/4) wth primary malignant melanoma less than 1.5 mm thick, 81%(9/11) with primary malignant melanoma more than 1.5 mm thick, and 100%(10/10) with metastatic malignant melanoma. The difference in p53 protein overexpression was statistically significant between benign nevi and malignant melanoma(p<0.01). Bcl-2 protein expression was observed in 73%(11/15) with compound nevus, 70%(7/10) with congenital melanocytic nevus, 75% (3/4) in primary malignant melanoma less than 1.5 mm thick, 54%(6/11) with primary malignant melanoma more than 1.5 mm thick, and 40%(4/10) with metastatic malignant melanoma. These findings suggested that mutation of p53 gene may be an important mechanism in the development of malignant melanoma. Although bcl-2 protein was expressed in cutaneous melanocytic lesion, no correlation was found between p53 protein and bcl-2 protein expression in malignant melanoma.
