Table 1 It shows study groups

From: Combination therapy of zinc and trimethoprim inhibits infection of influenza A virus in chick embryo

Group Virus load Treatment Number of embryos
group 1 10 EID50 Tri-Z: at Zn/TMP ratio 0.01 to 0.3, increment of 0.01 (30 ratios) 12 per ratio
group 2 100 EID50 Tri-Z: at Zn/TMP ratio 0.01 to 0.3, increment of 0.01 (30 ratios) 12 per ratio
C 1 10 EID50 .5 ml NS 12
C 2 10 EID50 Zn: 0.05 to 1.5 mg with 0.05 mg increments (30 concentrations) 12 per concentration
C 3 10 EID50 TMP: 5 mg 12
C 4 10 EID50 0.2 ml of convalescent serum 12
  1. We carried experiments examining effect of a mixture of trimethoprim and zinc influenza virus. We examined two virus loads 10 EID50 and 100 EID50, in 6 day old chick embryos, group 1 and group 2. This was compared to control groups (C 1- C 4). Experiments were repeated in triplicates. EID50 = egg infective dose 50 i.e. virus load that cause 50% mortality of the embryo, C = control, NS = normal saline, TMP = trimethoprim, Zn = zinc, Tri-Z: mixture of trimethoprim and zinc oxide
