Figure 1From: Cervical squamous carcinoma cells are resistant to the combined action of tumor necrosis factor-α and histamine whereas normal keratinocytes undergo cytolysisThe effect of histamine on the DNA content of SiHa cells. The cells were grown in incomplete or complete MEM and treated with indicated concentrations of histamine. The data are expressed as the percentage of the fluorescence in the control wells. Each bar represents the mean of individual quadruplicate cultures ± SE (n = 4). "*" denotes p < 0.05 when compared with the control values.Back to article page
