Background The temporal behavior of the coronary microcirculation in acute myocardial infarction may affect outcome. Diastolic deceleration time and early systolic flow reversal derived from coronary artery blood flow velocity patterns reflect microcirculatory function.

Objectives To assess left anterior descending coronary artery flow velocity patterns using Doppler transthoracic echocardiography after primary percutaneous coronary intervention, in patients with anterior AMI[1].

Methods Patterns of flow velocity patterns of the LAD[2] were obtained using transthoracic echocardiography-Doppler in 31 consecutive patients who presented with anterior AMI. Measurements were done at 6 hours, 36–48 hours, and 5 days after successful PPCI[3]. Measurements of DDT[4] and pressure half times (Pt½), as well as observation for ESFR[5] were performed.

Results In the first 2 days following PPCI, the average DDT, 600 ± 340 msec, were shorter than on day 5, 807 ± 332 msec (P < 0.012). FVP[6] in the first 2 days were dynamic and bidirectional: from short DDT (< 600 msec) to long DDT (> 600 msec) and vice versa. On day 5 most DDTs became longer. Pt½ at 6 hours was not different than at day 2 (174 ± 96 vs. 193 ± 99 msec, P = NS) and became longer on day 5 (235 ± 98 msec, p = 0.012). Bidirectional patterns were also observed in the ESFR in 6 patients (19%) at baseline, in 4 (13%) at 36 hours, and in 2 (6.5%) on day 5 after PPCI.

Background: In both adjuvant arthritis and rheumatoid arthritis edema and inflammation appear in synovial joints. Edema or effusion reflects an imbalance in lymph dynamics. Purified micronized flavonoid fraction is mainly used in the treatment of chronic venous insufficiency. This compound improves lymphatic drainage with a signicant increase in lymphatic flow and lymphatic pulsality. It is suggested that the beneficial effect of purified micronized flavonoid fraction may be involved in the treatment of adjuvant arthritis in rats.

Objectives: To evaluate the effect of Detralex on methotrexate prophylactic treatment of adjuvant arthritis in rats.

Methods: Groups of rats with adjuvant arthritis were treated with methotrexate (0.6 mg/kg/week), Detralex (20 mg/kg/day) and their combination for 50 days from adjuvant application. Hind paw swelling, arthrogram scores, serum albumin level, serum nitrite/nitrate concentrations, whole body mineral density and X-ray scans of synovial joints were evaluated as markers of inflammation and destructive changes associated with arthritis.

Results: Long-term prophylactic treatment with low dose methotrexate significantly inhibited the markers of both inflammation and arthritis. Detralex administered alone slightly decreased both the hind paw swelling and the arthritic score. Other inflammatory and arthritic markers were not significantly influenced. However, detralex combined with methotrexate markedly potentiated the beneficial effects of methotrexate, which resulted in a more significant reduction in hind paw swelling, arthritic scores, and serum concentrations of nitrite/nitrate. Interestingly, the arthritis-induced decrease of BMD[1] in AA[2] rats was significantly lower only in the group treated with the combination of Detralex+methotrexate.

Conclusion: Detralex increased the therapeutic efficacy of methotrexate basal treatment in AA. We suggest that this may be related to the beneficial effect of Detralex on microcirculation, especially on venules and lymphatic vessels.
