Pharmacological Investigation of the Wound Healing Activity of Cestrum nocturnum (L.) Ointment in Wistar Albino Rats

Table 3

Effect of EECN on tissue hydroxyproline content in excision wound model.

Group	Dry weight of tissues (mg)	Hydroxyproline content (g/100 mg tissues)
Group I (untreated)	42.66 1.13	27.50 0.71
Group II (ointment base treated)	44.31 0.8	28.13 0.92
Group II (standard)	44.33 2.0	34.50 0.84; a, b
Group III (2% w/w, ointment)	41.66 1.22	31.83 0.74; a, b
Group IV (5% w/w, ointment)	39.0 3.12	32.16 0.65; a, b

All values are represented as mean SEM, animals in each group. Data were analyzed by one-way ANOVA, followed by Tukey-Kramer Multiple Comparisons Test. a: significant difference as compared to untreated group (group I); b: significant difference as compared to ointment base treated group (group II), and P < 0.01, P < 0.001.
