Scanning electron microscope (Model; SEM ISI-DS-130) was used to observe the fine surface structures of the predominant cattle tick Haemaphysalis longicornis Neumann 1901 (Acarina: Ixodidae) in Korea and some SEM microphotographs were presented in this pictorial monograph. Brief descriptions of the main contents are consisted of followings; L Mean body size is 2.43mm in unfed males and 2. 58mm in unfed females, the eyes are absent. 2. The scutums are inornated but there are some short-setae on the surface of the body. 3. The festoons on the dorso-marginal part of the body are present and segmented with 11 sectors. 4. The cornua is well-developed and the bypostome dentition is usually 5/5 in both sexes but rarely 4/4 also seen. 5. There is no dorsal projection on the anteriointernal margin of the palpal article 2, howevever, there are well developed dorso-internal setae with setal fossa on it. 6. The joints of the legs (Coxatrochanter and trochanter coxa, etc) are well developed.

Axenfeld-Rieger syndrome is a rare autosomal dominant disorder characterized by various ocular and extraocular malformations. The incidence of Axenfeld-Rieger syndrome has been estimated to be 1 per 200,000. The syndrome is characterized by short body stature, delayed bone age, and deficient or arrested development of neural crest cells involving the anterior chamber of the eyes, facial bones, teeth, periumbilical skin, and cardiovascular system. This is a case of a 6 year-old girl, who came to the department of the pediatric dentistry, Yonsei University Dental Hospital, for evaluation and treatment of multiple congenital missing permanent teeth. The patient presented typical dental, craniofacial, and systemic features of Axenfeld-Rieger syndrome, such as glaucoma, oval pupil, heterochromatic iris, umbilical hernia, and delayed bone age. On the panoramic view, 3 primary teeth were missing and 13 permanent tooth germs were absent. On the lateral cephalograph, underdevelopment of the maxilla and normal growth pattern of the mandible were confirmed. Periodic dental follow-up is planned for evaluation and interceptive treatment of her dental and craniofacial problems. Denture or removable space maintainer with a pontic is considered for esthetic and functional restoration. In addition, orthognathic surgery is also planned in future to prevent further midfacial skeletal deformation. Early diagnosis of Axenfeld-Rieger syndrome is very important to prevent exacerbation of complications, such as glaucoma and skeletal deformities.

A 4-year-old, spayed female Maltese dog was presented for evaluation of acute onset of generalized tremor, right-sided head tilt, horizontal nystagmus, and mild ataxia with 4-day duration. However, the dog was bright, alert, and responsive. The neurological examinations revealed that bilateral horizontal-, positional nystagmus, and mild ataxia. Menace responses were also absent in both eyes. Typically, moderate generalized intension tremors were noted in four limbs and the head. No abnormalities were found in hemogram, radiography, and magnetic resonance imaging(MRI). Cytologic examination of cerebrospinal fluid(CSF) revealed a mild nonsuppurative inflammation. Thus, steroid responsive tremor syndrome(SRTS) was strongly suspected because of its inflammatory and idiopathic features. The dog excellently responded to immunosuppressive doses of corticosteroid. Therefore, we definitively diagnosed the dog as SRTS based on the exclusion of other causes of the tremor, clinical signs, and response to treatment. This is a first case report of SRTS in our country and we here describe clinical and neurological features in SRTS.
