NK cell markers and receptors have been discovered in many mammalian species, such as humans, mice, rats, pigs, and cows. However, there is still a lack of information concerning NK cell markers or receptors in canines. We have discovered that canine CD5-low density (CD5lo) cells in PBL are closely associated with NK cell characteristics. CD5lo cells comprised 14.9 +/- 6.68% of the total PBL. A high proportion of the CD5lo cell population expressed CD3 (96.6%), CD8alpha (77.7%), CD8beta (53%), alpha/beta TCR (83%), and CD11/18 (80%), but the expression of gamma/delta TCR (6.5%), CD4 (10.6%), and CD21 (2.4%) was low. CD5lo cells were larger than CD5-high density (CD5hi) cells. Light and electron microscopy revealed numerous large cytoplasmic granules in CD5lo cells, especially after IL-2 stimulation, which was in contrast to CD5hi, in which intracytoplasmic granules were not frequently seen. After IL-2 stimulation, CD5lo cells had significantly stronger NK cytotoxicity than CD5hi cells. CD5lo cells had much higher mRNA levels for NKG2D, CD16, CD94, CD160, perforin, and granzyme than CD5hi. Following IL-2 stimulation, CD5lo cells had significantly higher mRNA levels of NKp30, NKp44, CD16, and CD94 than CD5hi cells. In addition, IL-2-stimulated, CD5lo-depleted PBL showed a loss of NK cytotoxicity. CD5lo cells also showed significantly lower antigen-specific cytotoxic T cell activity as compared with CD5hi cells. Taken together, the CD5lo subset in canine PBL is closely related to canine NK cells, and CD5lo can be used as a phenotypic marker for an IL-2-dependent canine NK cell enrichment.

Pulse diagnosis were performed on 85 patients who came to the hospital for liver and gall-bladder problems. Correlation between liver tests, which include T-Bil, D-Bil, SGOT, SGPT, ZTT, Alp, gamma-GT, Cho, Alb, and ultra sound scanning, and pulse diagnosis were analyzed. 77 out of 85 subjects showed abnormal liver tests. We used the following 5 criteria for pulse diagnosis as liver abnormality to test the correlation: (1) C1 > or = 3+ and C1 + C4 > or = 4+ or C1 + C6 > or = 4 (in intensity); (2) C1 < or = 3 (in intensity); (3) C6 > or = 3 and C1 + C6 > or = 4 (in intensity); (4) C6 < or = -2 (in intensity) and C6 < or = -2 (in the phase) and (5) C1 > or = 2 C3 < or = -2 (in intensity) or C3 < or = -2 (in the phase). For C1 (liver) every 5% above normal was given one "+," every 5% below normal was given one "-." For C3 (spleen), C4 (lung), C6 (gall-bladder), every 10% above normal was given one "+,", every 10% below normal was given one "-." For the phase, every 10% delay in the traveling speed was given one "-." When considering only the "+" and "-" states and neglecting the quantity of "+" and "-," there are 2(11) (from intensity) x 2(11) (from phase), which equal 2048 x 2048 possible states in the pulse analysis. We considered only 5 criteria for liver abnormality; the correlation was still very high, p < 0.0002, kappa = 0.64. It strongly suggests that meridian theory and pulse diagnosis have physiological and pathological importance.

The accuracy rate for the first course of cancer treatment was affected by the cancer type and the experience of cancer registrars, but it was not affected by the workload of cancer registrars. We recommend that cancer registrars with basic licenses upgrade to advanced licenses as soon as possible. Medical record collaboration should establish documentation for checklist of radiotherapy and surgical operation records.
