Some new integral inequalities are given, and bounds of solutions of the following integro-differential equation are determined: ∫π‘₯β€²(𝑑)βˆ’β„±(𝑑,π‘₯(𝑑),𝑑0π‘˜(𝑑,𝑠,π‘₯(𝑑),π‘₯(𝑠))𝑑𝑠)=β„Ž(𝑑), π‘₯(0)=π‘₯0, where β„ŽβˆΆπ‘…+→𝑅, π‘˜βˆΆπ‘…2+×𝑅2→𝑅, β„±βˆΆπ‘…+×𝑅2→𝑅 are continuous functions, 𝑅+=[0,∞).
