Ajuvant effect of a Synthetic Aluminium - Magnesium Silicate on chloroquine phosphate, against Plasmodium berghei.

Abstract effect of a synthetic Aluminium - Magnesium Silicate (AMS) on antiplasmodial activity of chloroquine was tested. Plasmodium berghei-infected mice were treated with 7 mg/kg, 5 mg/kg and 3 mg/kg chloroquine, respectively. The two subgroups in each experiment were treated with chloroquine alone and with chloroquine in AMS respectively. Parasitaemia (%) of the group treated with 7 mg/kg was higher than that of the control. At 5 mg/kg, chloroquine treatment significantly reduced parasitaemia from 3.60 to 2.46 (P =0.01). Incorporating chloroquine in AMS significantly improved its ability to reduce P. berghei parasitaemia at 5 mgkg and at 3 mg/kg, from 2.46 0.21 to 1.57 0.25 (P = 0.01) and from 3.82 0.06 to 2.12 0.08 (P =0.01 ). It also increased mortality of mice treated at 7 mg/kg from 20 to 80 %

Aluminium - Magnesium Silicate enhances antibacterial activity of Ampicillin trihydrate, against Salmonella gallinarum

Solutions of different concentrations, of Ampicillin trihydrate (AT) and of a formulation of AT in Aluminium Magnesium Silicate (AMS), were used for sensitivity test on Salmonella gallinarum cultures. Also, S. gallinarum-infected chicks were treated with; 10 mg / Kg (AT), 10 mg / Kg (AT in AMS), 7.5 mg / Kg ( AT), 7.5 mg /Kg (AT in AMS). Mean inhibition area, 28.39 mm produced by AT did not vary significantly (P ) from 26.36 mm produced by AT in AMS. However, 17.5 105 Salmonella gallinarum culture forming units per ml of bile of the untreated chicks and 3.4 105 (80.58 % reduction), 2.5 105 (85.7 % reduction) , 5.4 105 (69.2 % reduction ) and 0.38 105 (97.8 % reduction ) of the respective treated groups, showed AMS significantly (P 0.01) improved AT`s ability to clear the infection, in vivo

Antiviral Effects of a Synthetic Aluminium-Magnesium Silicate on Avian Influenza Virus

Effects of a synthetic Aluminium-Magnesium Silicate (AMS) on Avian Influenza Virus (AIV) were tested. Equal amounts of H5N1 AIV samples and of AMS were mixed, left one hour, at room temperature before centrifuging. The supernatants were remeasured and tested for viral titre, for Mean Death Time (MDT) and Embryo Mortality Rate (EMR) of chicken eggs. Volumes of the viral samples reduced at rate of 23.4 ± 5.48 %. Viral titres reduced significantly (P from HA, 73 ± 32.72 to 1.4 ±0.43). Also, mortality of infected embryos reduced from 100 % to 65% while MDT of those that died, increased significantly (P = 0.001) from 76 ± 4.38 to 130 ±17.27 hours. When incubation with AMS was repeated on portions of the same sample, MDT increased from 64 to 104 hours with the portion incubated once. Two AIV portions on which incubation with AMS was repeated could not kill chick embryos
