The purpose of this study was to evaluate the changes and readjustment capacity in the hematological characteristics of the horse during and after a prolonged training program. One pony and two hot-blooded horses were used in this study. Resting or basal blood parameters were assessed by collecting blood samples of the animals for 1 to 2 months prior to start of the training program. Each animal was subjected to arbitrary exercise for 30 min by an automatic hot trotter and was bled at 0, 15, 30, 45 (15 min of recovery), 60 (30 min of recovery), and 75 min (45 min of recovery) after onset of exercise. All animals were exercised 3 times a week over a fivemonth period. Hematological parameters including average white blood cell counts (WBC, ${\times}$$10^3$/$\mu$l), erythrocyte concentrations (RBC, ${\times}$$10^6$/$\mu$l), hematocrit (HCT, %), mean corpuscular volume (MCV, fl), number of platelets (PLT, ${\times}$$10^4$/$\mu$l), hemoglobin concentration (Hb, g/dl), mean corpuscular hemoglobin (MCH, pg), and mean corpuscular hemoglobin concentration (MCHC, g/dl) were analyzed using an automatic cell counter. All animals showed that RBC, WBC, and HCT were significantly (p<0.05) increasing from 7.09, 8.55, and 43.5 to 8.11, 9.67, and 49.5, respectively, during the 30 min of exercise and were back to or lower than the initial basis (resting and 0 min) 30 min after exercise. However, no significant differences were detected in MCV (50.3-51.3 fl), MCH (17.2-17.4 pg), and MCHC (33.7-34.4 g/dl) values (p>0.05) regardless of the training periods. Similar trends were observed after 1, 3, 4, and 5 months of training when compared to the resting state. When these parameters were analyzed by the effect of training periods (month), mean WBC concentrations significantly reduced in the fourth and fifth month after onset of training compared to that in resting condition or the first month of training program (p<0.05). The RBC values elevated at the second month (9.40) and reaching a significantly low level (p<0.001) at the fifth month (8.62) after training compared to the first month of training (7.89). In conclusion, a mild training program enhances blood parameters gradually in both the horse and the pony. Therefore, an optimized training program is beneficial in promoting the endurance performance of the horse.

Objectives : The aim of this study was to evaluate the distribution of tongue color and the correlation of the tongue colors with clinical laboratory parameters. Methods : Statistical analysis on the frequency of each tongue color and the results of the clinical laboratory parameters in each tongue color group. Results : Tongue colors that appeared most frequently were 702c, 695c, 493c, 694c, 701c, 500c, 7432c, 7431c, 7634c, 7419c in that order. Following them, 494c and 507c were rarer colors, and 501c, 673c, 687c, 693c, 696c, 703c, 7418c were equally rarest colors. Among each tongue color group, a significant difference was found in the result of complete blood cell count (CBC). The level of red blood cell (RBC) of 7432c group was significantly higher than that of the other groups except 694c group. The level of hemoglobin (Hb), hematocrit (Hct) of 7432c group were significantly higher than those of all the other groups. The level of RBC of 7431c group was lowest and significantly different from 694c, 7432c group. In results of the other tests were not significantly different. However the level of total cholesterol was higher in 695c, 694c, 500c group, and the level of triglyceride was higher in 500c, 7431c, 694c group. Those four colors have a low chroma and 7431c, 695c take blue violet color. Conclusions : The tongue color is distributed throughout following colors by order of frequency: 702c, 695c, 493c, 694c, 701c, 500c, 7432c, 7431c, 7634c, 7419c, 708c, 494c, 507c, 501c, 673c, 687c, 693c, 696c, 703c, 7418c. Some parameters of CBC has a significant correlation with some tongue colors. Other results including lipid profile, renal function test, and liver function test had no significant difference according to tongue color. However, the colors which have low chroma or take blue violet color tented to be higher in the levels of total cholesterol and triglyceride.

The present study was designed to investigate i) the action of various nucleotides on membrane permeability of rat red blood cell and hepatocyte for $Na^{+}$ and $Rb^{+}$ ii) the characteristics of purinoceptors on these cell membranes. Blood from Sprague-Dawley rats was obtained by carotid arterial cannulation. Red blood cells were then washed 3 times with saline at $4{\circ}C$. Hepatic parenchymal cells were isolated from rat livers by using a modification of the Berry and Friend (1969) method. For the $Na^{+}$ influx studies, isolated RBC and hepatocyte were incubated in incubation medium containing $^{22}Na^{+}0.2\;{\mu}Ci/ml$ at $37^{\circ}C$. After various time intervals samples were removed from the incubation flask and washed out 3 times with ice-cold washing solutions. Cells were destroyed by adding Triton X-100 and TCA solution. After centrifugation, the supernatants were assayed for $^{22}Na^{+}$ by gamma counter. $^{86}Rb^{+}$ was used to simulate $K^{+}$ in these $K^{+}efflux$ studies. Isolated hepatocytes were incubated for 60 min in the loading solution containing $^{86}Rb^{+}\;10\;{\mu}Ci/ml$ at $37^{\circ}C$. After loading, the cells washed out 3 times by centrifugation with washing solution. The cells were incubated in buffer solution at $37^{\circ}C$. At intervals thereafter, samples were removed and centrifuged. The supernatants were analyzed for $^{86}Rb^{+}$ by liquid scintillation counter. The main results of the experiments were: 1) ATP and ATPP increased in both $^{22}Na^{+}$ influx and $^{86}Rb^{+}$ efflux in the red blood cell. Although ADP showed a tendency to increase in RBC membrane permeability for $^{22}Na^{+}$ and $^{86}Rb^{+}$, the changes were not significantly different from the control. 2) The Significant changes in $^{22}Na^{+}$ and $^{86}Rb^{+}$ flux by ATP were also demonstrated in hepatocyte. ATPP and ADP showed a tendency to increase in hepatocyte membrane permeability for both ions. 3) Other nucleoside triphosphates-ITP, GTP and CTP-did not change in membrane permeability for $^{22}Na^{+}$ and $^{86}Rb^{+}$ in RBC and hepatocyte. In conclusion, not only ATP but also ATPP activate purinoceptors and change in membrane permeability for $Na^{+}$ and $K^{+}$. In order to activate purinoceptors on the cell membrane, the nucleotides have to possess intact adenine moiety and three phosphates or more in its molecule.

Centroceras gasparrinii is characterized by 1) straight spines, 2) an ovoid gland cell, 3) tetrasporangia with involucral branchlets, and 4) ovoid cortical cells on the first and second cortical initials. A similar Centroceras species with dichotomous habit, "Centroceras clavulatum", has been widely known as a common species of Korean marine flora. However, the species known as "C. clavulatum" in Korea is recognized as C. gasparrinii based on the molecular and morphological evidence. Newly generated sequences of rbcL gene reveal that all taxa of Centroceras from Korea having dichotomous branching pattern are C. gasparrinii. There is 0-0.07% sequence divergence among specimens of C. gasparrinii in Korea. "Centroceras clavulatum" is excluded from Korean flora and C. gasparrinii is included instead of "Centroceras clavulatum". C. gasparrinii also differs from C. distichum in Korea in that it has tetrasporangia with involucral branchlets and dichotomous branching pattern, while C. distichum has immersed tetrasporangia and an alternate branching pattern.

1. Purpose Stroke is the most frequent cause of mortality and morbidity rate in Korea with coronary heart disease and cancer. The ischemic type of stroke is increasing tendency. The purpose of this studies is to examine the hematologic difference between cb infarction patients and Korean normal adults. 2. Method The study group consisted of neurologically confirmd 50 cb-infarction patients as the case group and 278 patients as control group that they had no significant result by CT through early examination of stroke in Cheonan oriental hospital of Daejeon university. We tested and compared RBC, hemoglobin, hematocrit, WBC, PT, PTT, total protein, albumin, total bilirubin, direct bilirubin, GOT GPT, $\gamma$-GTP, total cholesterol, triglyceride, HDL-C, glucose, BUN, creatinine, Na, K in the both group. 3. Result In the sample group(cb infarction group), there were many patients with low RBC count but no significant and with low hemoglobin, hematocrit(p<0.05). Thereas, increased WBC count and delayed PTT were showed respectively 20%, 36% in patient group, 7.9%, 4.7% in normal group(p<0.05). Comparing the LFT between cb infarction patients and normal adults, we founded significant cases with low HDL-C level, high glucose level, low potassium level in patient group(p<0.05). But the percentage of high total cholesterol level and triglyceride level were 18%, 29%(norma1 group), 20%, 28%(cb infarction group) respectively, there were no significant difference. 4. Conclusion In this study, we demonstrated that low HDL-C level and high glucose level is one of important risk factor of cb infarction. Also prospective studies are needed to evaluate many risk factor(hemoglobin, hematocrit, WBC, cholesterol, triglyceride, K, etc) of cb infarction.

본 연구에서는 넙치(Paralichthys olivaceus)를 이용한 고ㆍ저온에서의 혈액 생리학적인 변화뿐만 아니라 항산화 효소인 CAT 및 SOD등의 효소 변화를 조사하여 스트레스에 대한 생리적인 변화에 대한 지표를 설정하고자 실시하였다. 실험어는 평균 전장의 29.0$\pm$1.5 cm, 평균 중량 246.5$\pm$25 g인 것을 사용하였다. 실험구는 각각 15$^{\circ}C$, 2$0^{\circ}C$(대조군), $25^{\circ}C$ 및 3$0^{\circ}C$로 설정하였으며, 실험 개시 후 1, 2, 4, 6 및 8 hr후에 혈액성상을 분석하였다. 측정항목으로는 헤마토크리트(Ht)수치, 혈색소 농도(Hb), 적혈구 수(RBC), 코티졸, Catalase (CAT) 및 Superoxide dismutase (SOD)를 각각 측정하였다. 실험결과 아가미 운동은 대조구에 비해 3$0^{\circ}C$ 및 $25^{\circ}C$ 에서 유의한 증가를 나타내었고, 저온인 15$^{\circ}C$ 및 1$0^{\circ}C$에서는 감소하는 결과를 보였다. Ht수치는 3$0^{\circ}C$에서 실험 개시 후 6시간까지 높은 값을 나타내었으며, $25^{\circ}C$에서는 1 시간까지는 증가하였다가 이후 6 시간까지는 감소되었다. 그러나 저 수온인 15$^{\circ}C$ 및 1$0^{\circ}C$에 서는 전체적으로 감소된 값을 나타내었다. RBC는 3$0^{\circ}C$ 및 $25^{\circ}C$에서 전반적으로 증가하였으며, 저 수온인 15$^{\circ}C$는 4 시간까지 낮아지다가 이후 증가 되었다. Hb농도는 3$0^{\circ}C$및 $25^{\circ}C$에서 전반적으로 증가하는 경향을 보였으나 4 시간째 일시적으로 감소하는 경향을 보였다. 15$^{\circ}C$에서는 4시간째까지는 감소되었다가 6 시간째에는 높아지는 경향을 보였다. 이러한 증가된 경향은 온도가 높아질수록 용존 산소의 포화도가 낮아져 산소부족 요인에 의해 적혈구수의 증가와 함께 Ht수치도 높아지며 아가미운동을 통한 혈액으로의 산소운반이 능동적으로 이루어지고 있음을 나타내고 있다. 혈장 코티졸의 농도는 $25^{\circ}C$에서는 증가하는 경향을 보였으며, 1$0^{\circ}C$및 3$0^{\circ}C$에서는 1 시간까지 증가되었다가 회복되는 경향을 나타내었다. 신장에서의 SOD활성은 $25^{\circ}C$인 경우 대조구보다 높은 값을 유지하였다. 하지만, 30도에서는 4 시간째까지 증가하는 경향을 보였으나 이후 감소하는 경향을 보였으며, 저온인 1$0^{\circ}C$에서는 감소하였다. 간장에서의 CAT의 활성은 3$0^{\circ}C$인 경우 4시간까지 $25^{\circ}C$ 및 15$^{\circ}C$에서는 2 시간까지 증가하였다가 이후 낮아지는 경향을 보였다. 이상의 결과로 고ㆍ저 수온변화에 따른 스트레스가 장기화될 경우 어체의 건강상에 문제점의 발생하여 대량 폐사 및 질병발생의 야기될 것으로 사료된다.

This study was to evaluate the antioxidant properties of the leaf extracts of Diospyros lotus (DLE) on the chemical-induced free radical and rat red blood cell (RBC) oxidative damage in vitro. DLE were prepared by extracting with water. DLE showed the high antioxidant activities on the scavenging of 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid)-induced radicals. An antioxidant activities of DLE was similar to the reference antioxidant butylated hydroxytoluene (BHT) and (${\pm}$)6-hydroxy-2,5,7,8-tetramethylchromane-2-carboxylic acid (Trolox). Reducing power of $1,000{\mu}g/mL$ DLE also was similar to the vitamin C. In RBC, oxidative hemolysis induced by the aqueous peroxyl radical generator (2,2'-Azobis (2-methylpropionamidine) dihydrochloride (AAPH)) were significantly suppressed by DLE in a dose-dependent manner. Furthermore, DLE prevented the depletion of cytosolic antioxidant glutathione in RBC damaged with AAPH. These results suggest that DLE may has value as natural product with its high quality antioxidant properties against oxidative stress.

Thorea indica sp. nov. is described from the Sai River, Uttar Pradesh, India (26°39′00.7″ N, 80°47′38.3″ E). Its classification is based on molecular sequences of the plastid-encoded RuBisCO large-subunit gene, rbcL and the barcode region of the mitochondrial encoded cytochrome c oxidase subunit 1, cox1, and morphological data. The sequence analyses confirm a new species of Thorea. The cox1 barcode sequence had 90.4-90.8% identity with Thorea sp. from Australia and Thorea hispida from Hawaii and China. Based on rbcL sequences the Indian specimen was positioned in a major clade with high support (>95 bootstrap and 0.95 posterior probability) containing two other species: T. okadae from Japan and T. hispida from the continental USA, Hawaii, the UK, and China. The divergences among these sequences were T. indica vs. T. okadae (2.8%) and T. indica vs. T. hispida (2.9-3.4%). The comparison of morphological characters of Thorea from India was not conclusive due to the inadequate descriptions in previous reports: most specimens reported as T. hispida fit within the circumscription of T. indica as described here. The previous report of T. siamensis from the Sai River is incorrect and the specimens fit within our description of T. indica. Thorea indica and T. okadae can be distinguished by minor morphometric characters and sexuality (dioecious vs. monoecious).

A total of 109 heads of horses and ponies from eight horseback riding clubs nearby Central Taiwan were investigated to evaluate the blood parameters and the biochemical compositions of serum for the documentation of clinical pathological diagnosis and exercise physiology. Blood samples were collected from the jugular vein of resting horses. The sex difference in the blood traits were compared both in horses and in ponies. Results shows that total plasma proteins (PP) and hematocrit (PCV) were found higher in male horses than in females (p < 0.05). The sexual effect also exertes a significant influence on the leucocyte (WBC) count, but not on the erythrocyte (RBC) concentration. According to the differential counts of leucocytes, the number of monocytes and lymphocytes was higher in the male pony than that of in male horse. A close relationship Between the erythrocyte sedimention rate (ESR) and the other blood parameters were found especially in PCV, RBC concentration, and plasma protein level. The average ESR observed at 60 minutes were $21.80{\pm}21.87mm$, $39.50{\pm}18.90mm$ and $43.73{\pm}17.89mm$ in stallions, geldings, and mares, respectively. Most of the biochemical components of horse serum detected were distributed in normal ranges, although some of the items show a great variation in such a large sample size.
