Trichinellosis is a parasitic zoonosis of public health importance. It is caused by Trichinella spiralis which has a wide host range including humans. In the present communication, the ELISA technique was employed on a total of 803 blood samples from 7 selected pig breeding farms in 1996 for diagnosis and surveillance of trichinellosis. Out of the entire 803 samples, nine were found to be suspected while one was positive by ELISA. But western blot analyses employed for further confirmation have shown that all of 10 samples did not react to larval excretory-secretory product antigens. These results indicate that pig breeding farms included in the present study are free from trichinellosis. However, it does not mean Korea is free from trichinellosis since human trichinellosis has recently been reported. The necessity of continued surveillance for trichinellosis in both pigs and wild animals was discussed.

2.Scanning electron microscopic observations on the surface structure of the tick Boophilus microplus(Canestrini, 1887) female specimens.
The Korean Journal of Parasitology 1985;23(2):313-323
Boophilus microplus (Canestrini, 1887) female specimens were subjected to scanning electron microscopy for the observation of surface fine structures. Morphological characteristics observed were summarized as follows: The palpi were wider than long, and compressed, ridged dorsally and laterally. There were usually four pairs of ventro-internal setae on the articles. The hypostome dentition was usually 4/4 but occasionally 5/5. The basis capituli were hexagonal dorsally and the porose area was distinct with the holes developed well. There were numerous folds resembling finger prints around the female genital pore. A pair of anal lobes with specified setae on them was also recognized as one of the morphological characteristics.

3.A description with scanning electron microscopy on the tick Ixodes persulcatus (Schulze, 1930 ) male and female specimens.
The Korean Journal of Parasitology 1985;23(2):305-312
The surface fine structures of Ixodes persulcatus (Schulze, 1930) male and female specimens were observed by means of a scanning electron microscope. A brief review on the biology of the ticks and their disease relationships was also presented. The sexual dimorphism of the specimen was marked; the male was quite smaller than the female. The genital groove was well developed and deep, the anal groove was distinct and characteristically extending anteriorly around the anus. The 4th article was much reduced and situated on the top of the 3rd article ventrally. The hypostome dentition was usually 3/3. The bottom of the basis capitulum of the male specimen was strictly straight in shape. This species was regarded as one of the most important vectors for infectious diseases of migrating birds.

The occurrence of tick bites and related dermatoses have been rarely described in Korea. Ticks may cause various infectious diseases associated with dermatoses by transmission of the mediating pathogens such as virus, bacteria and rickettsia. We describe herein, to our knowledge, the first tick bite with Ixodes monospinosus in Korea, The patient, a 64-year old male, was bitten by a tick while climbing a mountain which is located in the Kanghwado. He had an asymptomatic, yellowish pea-sized tick attached on the right antecubital area for 7 days' duration, which was identified as an adult female of I. monospinosus by the scanning electron microscopic examination.

Purpose:
Generally, the treatment of ankle trimalleolar open fractures is divided into two stages: external fixation and debridement; and secondary internal fixation. On the other hand, this two-stage operation takes considerable treatment time and is challenging in procedures requiring reduction. The purpose of this study was to evaluate the radiologic and clinical results of an immediate one-stage internal fixation operation considering the wound conditions to overcome two stage operation disadvantages.
Materials and Methods:
From September 2009 to January 2018, 24 cases of ankle trimalleolar open fractures, who underwent immediate internal fixation and were followed up for at least one year, were studied retrospectively. The open wound was divided into the Gustilo- Anderson classification. Open reduction and internal fixation were performed on every medial and lateral malleolar fracture. On the other hand, with posterior malleolar fractures, surgical or conservative treatment was performed depending on the fragment size. The radiologic outcome was evaluated using the Burwell and Charnley criteria and American Orthopaedic Foot and Ankle Society (AOFAS) scores, and complications, such as infection and posttraumatic arthritis, were used for the clinical evaluation.
Results:
The wound was classified into eight cases (33.3%) of type I, 11 cases (45.8%) of type II, and five cases (20.8%) of type IIIa. The degree of reduction was anatomical, fair, and poor in 16 cases (66.7%), six cases (25.0%), and two cases (8.3%), respectively. The mean AOFAS score was 79 points, and there were complications, such as infection in three cases (12.5%) and post-traumatic arthritis in two cases (8.3%).
Conclusion
Satisfactory results were obtained through immediate surgical treatment in ankle trimalleolar open fractures of types I, II, and IIIa.
