Figure 3From: Effects of low-intensity pulsed ultrasound and hyperbaric oxygen on human osteoarthritic chondrocytesEffect of HBO and LIPUS on transcription of iNOS. HBO suppressed while LIPUS increased the gene expressions of iNOS in OA chondrocytes (*p < 0.05). HBO combined with LIPUS treatments resulted in compensatory effect in the iNOS expression.Back to article page
